My 8 week old Barred Rocks are peaking my 8 week old Araucanas. They have been raised together and this is the first time I've had trouble. The coop is 16' X 10' and I have 40 birds. They have not been outside yet because of the cold and snow. Woke up this morning and went to fill the feed and 3 Araucanas had tail feather that had been peaked at severely. Should I trim peaks? I know a lot of people frown on that idea, but I'm afraid I'll lose chickens if I do not. They have seemed very happy up until this point. Any suggestions for a new small chicken farmer?
