My neighbors have chickens and I have not seen my neighbors in about a week (we did not see them often, this isn't a chummy neighborhood). I was worried about the birds so I went over and peeked in the windows and it looks like they moved out (in a hurry). Their birds showed up about a week or two after I got mine, so I guess they are around 14 weeks old? They don't appear to be laying yet. Anyways, I checked on the birds (they were confined in their coop) and some are dead and have been ?hollowed out? from the rear end. One had an exposed tail bone and not much rear end left and died in my arms. Another has a bleeding rear end but was up running around with the other birds. I isolated him/her and I don't think the others are injured. I gave them food, grit, and water and I'm trying to build them a shelter and yard on my property to move them to. I am not sure what else I can do for the bleeding bird, the drops of blood have slowed since I isolated it. Any advice?
