I went out tonight to tuck the girls in and there are spatters of blood in the shavings and on the wall. Upon closer inspection it looks like one of them has a bloody comb. She is the lowest on the totem pole and I am nervous for her. Are they pecking for the sake of pecking? Or are they making a point or what? Will they just keep at it until she dies? She seems fine (except for the bloody comb) - but what the heck? Should I do something? I only have four chickens. I have been checking combs obsessively because I have one with a touch of frost bite. But, this is not that chicken. None of the other three had frostbite for sure - they all have tiny little walnut combs. (except the barred rock who has the frostbite) So, I know they aren't picking at her comb because she has frostbite. But, whatever the reason - they are drawing blood. What can I do?
