I posted this yesterday https://www.backyardchickens.com/forum/viewtopic.php?id=357087 and when we were out picking blackberries, my son (7) came running out to me asking if it was normal for a chicken to have a bloody bottom. I tell him to go catch the one he is talking about and i am coming. I get over there and he has caught our Welsummer Roo (about 8 weeks or so in age) and his entire back tail end about the size of a silver dollar area is bloody, and raw, and you can see the skin pulsating...sorta looks like those pictures you see of a heart, how it is contracting...the area is doing that, i think it is around where his poo comes out and you can see the straw part of the broken off feathers that are still attached and it is just gruesome looking He is panting and i immediate removed him to a cage near by but separated from the rest of the flock with his own food and water. I don't know what to do? will he survive? Do i treat his wounds (that just makes me shudder)..... Please, i am a total newbie and this is my first disaster and i have only had chickens for about 3 - 4 weeks now. Thanks everyone!
