I had that happen too, after several days I finally found the chicken who was bleeding ... she had lost a toenail ... tore it off somehow and it just kept bleeding. It did eventually stop.Okay everyone, I know I should ask this in the Emergency thread, but it takes forever to get answer. When I went out this morning to let everyone out of the coop and feed. I noticed a lot of blood on the ground. (don't know if it was there last night, old man locked up birds and he just isn't observant, I checked every hen out there, especially the ones right over it, no one had blood on them. I thought well maybe they killed a mouse, well while feeding I noticed blood again on the ground. NO ONE acts like they could have lost that much blood without dying. So what could it be and how can I find out who it is, if all are acting normal and upon physical inspection of all birds no blood was seen. What could it be?
