My 6 wonderful Isa Brown hens are not not doing too good. I started getting some bloody eggs. Not all of them. They were having all their eggs in a plastic tote, and were doing fine. Something changed. They started having them under the ramp that leads to the outside (on the inside of the coop). I dont have a lot of money at all, so I work with what I got. This morning one girl was shaking her leg like she was cold (though its kept at 40-50 degrees in the coop) she pooed with a squritng sound, and all the other hens were coming over to peck her bottom. I dont know what to do. We just put up 2 new hen boxes that are made out of those plastic milk crates, but they just have not found them yet. I took the ramp away, so they do not have the idea of going under it to have their eggs anymore. When they use to go under it, they would get pecked from the back. Thats the only place besides their back feathers, they are getting pecked from. Thus the bloody eggs. I give them fresh water, layer with grit and schell and a cake of suet everyday. I dont have room to divide them up, nor a pet carrier. I dont know what else to do. Can I put a medicine in their food to help them? I please welcome your advice. Thank you.
