I unfortunately have had 3 Chickens to get killed by my next door neighbors dog. 2 others have been injured. This is going on 3 weeks now. One of the chickens that was injured will look fine one day and the next day like he/she can barely move. I don't know if it is a hen or a rooster yet. I'm brand new to this entire thing. Got baby chicks for Easter for my kids and now I love them just as much as they do. Anyway, the chicken has diareah and looks kinda pale. Do you think that it has internal injuries and if so, should I keep letting it suffer or see if it will recover fully? I don't really see any wounds that are terrible except for a wrip in the top of the wing. I don't think that will ever heal and if it is even possible for it to heal. Do you think it is still in shock? Please help, I just don't know what to do.
