Cochin Chick Gender- Development Pictures

Summer 2010, we ordered bantam cochins, and they aren’t sold sorted by gender at day old because of their tiny size.   We had 13 straight run chicks.    I have read around that most of the time gender in bantam cochins is pretty easy to determine between 4 and 6 weeks, and that the males feather in much slower than the females on the back, tails, and wing bows especially.  I am no expert on chicken sexing, but I am trying to keep track of their development with notes and pictures.  Here  is one place I checked to see what I should be looking for: Clues to Gender and cochins are Asiatic, but it doesn’t say it works with bantams.  They are also called Pekins in the U.K. where the Pekin breed is one of the most popular for backyard chickens.

Update: 8/5/2010  We sold 7 of the chicks today.  They went as a group to North Hollywood High School Agricultural Department.  The school has a beautiful multi acre farm.  I was very happy to find a place that the boys were welcome to stay and not all be automatically named “Stew.”  We now have 6, two of each breed.  We kept the largest partridge.  There is a very good chance it is a male due to the fact it is already pink combed and has tiny waddles.
Update: 8/30/10 The pretty partridge did end up being a male.  He only crowed softly and very infrequently, but I decided to find a new home for him before it got too hard to let him go.
  • Basically, I saw no indicators of gender at 3 days old when they arrived.
  • The black cochins bantam cockerels started showing male traits at two weeks old.  The black cochins males were the only variety to demonstrate all the signs I was looking for: slow feathering on wing bows, tails and backs, plus pink combs early.
  • The partridge chicks looked all exactly the same until sometime between 6 and 7 weeks old.  Then, the boys feathering colors started to change and be more dramatic and colorful.  Before that, the patterns were all kind of barred looking.
  • The buffs were the hardest.  Both sexes feathered in at the same rate.  It wasn’t until the comb developed on the one male at 6 weeks, that I noticed any differences.
  • I have a long way to go before I can sort cochin genders any earlier than 6 weeks.
  • If you have any suggestions for determining cochins’ gender, please email me…I would appreciate the help since we love Cochins.

Black Bantam Cochin chicks - less than a week old

Black Bantam Cochin chicks - 3 Weeks old (there are two cockerels. they are on either end of this photo

Black Cochin cockerels 6 weeks old. These two moved to the Ag Department at North Hollywood High School along with 1 buff pullet, 1 black pullet, 2 partridge, and the other unknown gender buff.

Black cochin chicks - 6 weeks old - These 3 turned out to be pullets. We kept the two on the sides. Penguin is on the bottom left and Lady Cluck on the right. The middle one went to a new home at 6 weeks with 6 others.

Buff Bantam Cochins - Less than a week old

Buff Bantam Cochin Chick -3 weeks old - none of the others would cooperate for a photo. I think this was the cockerel.

Buff Cochin chicks - 6 weeks old -one pullet, and one that is a little pink in the comb is a cockerel. At six weeks, the male went to the Ag Dept. The pullet on the left is Missy Prissy/ Greasy Chicken

Two of the four Buff Cochin chicks - 6 weeks old - both pullets. We kept the one on the right, Daisy.

Partridge Bantam Cochin Chicks - Less than a week old

Partridge Bantam Cochin chicks - 3 Weeks old, All feathering similarly and very quickly. The pullet is second from the left. I remember because she had the least amount of foot feathering of the 4 chicks.

Partridge cochins - 6 weeks, one has a slightly different pattern than the other three, kind of barred, not yet pencilled. The rate of feathering was the same in all four, but three were slightly darker in general and more burgundy in the hackles. We had one pullet, Harley, and she was the one with more barring, less gray, and not much foot feathering; the one in front left, but we didn't know it for sure for another week after this photo was taken.

    • I too have 3 show breed buff Pekin bantams from German champion Pekin/Cochin bantam breeder Gerrit Bosch. From eggs I hatched only three out of ten sent. The birds are feathered nicely.The only difference showing is one is longer than the other two.6 weeks today they have hardly any comb and even though I have a flock of them as garden birds I still cannot tell. Buffs are so hard to tell apart and I only hope I do not have 3 cockerels and hope for 3 hens in prayer. I hate killing anything so lovely but infested once with five cock birds i say never again. I keep just six mixed coloured Pekin bantams with a red partridge Cock bird. I wanted buff hens as thee of my mixed are now 5 years old and stopping lay. If 3 hens all will be perfect.

  1. Great pics. I was hoping you could identify which was the female of the bunch in the Partridge Cochin chick picture. Thanks!

    • I don’t know in the “less than a week old picture” of the partridge chicks, which is which from that photo. In the 3 week old picture, she is also in the front row on the left/ or if counting bodies left to right, the pullet is the second from the left. She had the least amount of foot feathering out of the 4 chicks.

  2. I have a standard size partidge cochin chick. She’s at least 2 weeks old. She’s larger, more alert, and less feathered than our black cochin chick who is the same age. Even our week old EE has a bit more feathers. Do partridge cochins usually feather slowly?

    • Hi Austin,
      I haven’t raised any LF (large fowl standard size) Cochins. My experience with bantam Cochins, Pekins, is the males sometimes feather in slower than the females of the same color variety. However, I have raised a few varieties, like silver pencilled, which is similar to partridge, that the females feather in really slow. My first two pullets of those were still pretty fuzzy at 7 weeks old. The self blue Cochins also are really slow at feathering in, in both genders.

      With the partridge bantam Cochins i have raised, the boys and girls both feather in at the same rate and look pretty similar until about 6 or 7 weeks old. At two weeks old, they usually have a few tail feathers, some wing primary feathers, and a few shoulder feathers, but the rest is bare/ fuzzy. If your chick is thriving and growing otherwise, I wouldn’t worry too much, especially when comparing her to the Easter Eggers or other colors.

      • Thanks for the response. I am wondering also what the differences are between bantams and large breeds, despite size of course. All I see right now is wing feathers and a bit of leg feathers. She’s very active, has her comb coming in, and stands taller than the other two. I wonder if you were able to observe this in your partridge cochins. I’ll just sit tight for now. I know what to look for, just gotta wait for it.

  3. Just hatched six mixed cochins (buff cochin father). All have light down /feathers on legs. 1 black, 2 yellow, 3 red. I got the eggs from my in-laws farm. They moved from the city and bought 50 acres in S. Ga.
