Chick Feather Growth or Pecking Cannibalism.

I am trying to figure out if this is the chicks just losing their fir or if its from other chicks pecking at my chicks feathers. I have pictures at the bottom of the new chicks feathers.

I got a batch of chicks about 3 weeks ago. So they are about 3-5 weeks now. 2 Golden Sex links (no pecking that I've seen), 2 White plymouth rocks (no problems) and two barnyard bantams which occassionally peck my new young chicks. Just got another batch that's been with other chicks for day two now. The two concerned ones are my 1 D'Uccle bantam, 1 Frizzles bantam. The others new chicks were an americauna which I've seen peck at the frizzle feathers before along with a welsummer and barred plymouth rock. All just a few days old.

I have seen when i first introduce them the two older bantams (about 3-4 weeks old) peck the younger ones where they squeak loud but have not seen any feather pecking from them. So being new to raising chickens I don't know how much is normal shedding and growth versus pecking/cannibalism.

Any advice would be great. Loving the chickens already. They are in the upper layer of the coop in my garage currently.

Thanks!

Combining chicks that different in size commonly results in the bigger ones picking on the little one, sometimes to the point of death. You may want to consider brooding the new chicks separately until they are closer in size and then introducing tge two groups to each other.

I cannot see the feather lose you are talking about, but I personally wouldn't brood young chicks with older ones, they require different temperatures and the bigger ones could seriously injure the young ones. The older ones are nearly fully feathered and should be getting weaned off extra heat.

I should of picked up the chick and show the feathers closer. I have been watching them more. The only ones I've seen peck at it is the welsummers and mostly the Americana. Both are chick's.

I debated doing them separately but just know it's easier to introduce them younger. I have seen others do it this way. I keep one side around 85-95 and the other side is around 70-75 fluctuates a little especially as temperature drops at night.

The missing feathering is most seen on the gray chick. I was hoping not to have to brood separate but definitely will if it comes to it.

I'm only using half the coop. I'm going to use a piece of plywood to create a floor in my second half as its on the concrete right now and open the door to see if this helps. It will give them more space and a colder area with no heat source. I added a closer look of the feathers to look at.

That is just how the feathers look when they come in, they are encased in a sheath. They aren't being pecked.

Thanks. You were right. The feathers have grown a lot in two days. The chicks were just so tiny I was a little worried. They are getting along fine with the other chickens. They seem to only eat from the ground and not the feeder. May have to wait till they are a little bigger. Once my fence is in next week I'm putting them all outside .
