Have another Delaware hen who has now begun to bite everyone's comb, this is not something she used to do but lately she goes after other chickens and chases and bites them. We put her in detention for 2 days in the coop but not with the others and tried to see if things would be different today but no luck. We did order some pinless peepers but won't get them probably for several days, should we leave her alone in the separation area until they get here? Is winter time making birds start biting or feather picking more than the warmer months? I'll never have another Delaware again, both have been white devils.
