One of my two barred rock chickens is getting pecked on the comb. She has pocked scabs all over her comb, and a couple on her wattles. This has been going on for about 3 weeks now, and it seems to be getting worse not better. Should I isolate her from the flock? If so, I am thinking to do so by putting her inside a dog crate inside the coop, so that she won't be completely out of the social order (just not being pecked). Any advice? I have 4 chickens - 2 BR, 1 NHR and 1 EE. The one BR is the only one with any signs of pecking or scabs. Thanks in advance. Edited to add: the gals all just started laying about the time the pecking problem showed up. They are now about 29-30 weeks old.
