I have 10 Barred Rock pullets that are almost 20 weeks old and 14 chicks that are a combination of CCL, BLRW and SBELs that are 15 weeks old. Five of those are cockrels and the rest pullets. I notice that there are feathers here and there all the time but none of them ever appears to be noticably missing any.In fact the BRs are quite fluffy. I have not as yet gotten anybody laying eggs. The older ones do chase the younger about on occassion and could be pulling out a few feathers. Is it normal for them to lose feathers at random just like we lose hair and it just seems like a lot because there are 24 of them? About half of the Barred Rocks have really red combs and wattles. The others have smaller and paler combs. None of the other 14chicks looks mature at all except for the males. They also chase each other a bit but no real aggression, at least not yet. There is plenty of room for them to stay out of each others way for the most part. They are fed fermented organic grower feed and treats of fruits and veggies on occassion like tomatoes, watermelon rinds, strawberry caps and cantaloupe rinds.
