Bleeding from back passage

Help please, Ive just called my girls in for the night and one of them is bleeding from her back passage, it looks  as if she may have a prolapse, but when I  gently press it the swelling goes in.  Her breathing is quite fast but otherwise looks well with a lovely bright red comb and wattles. For  the moment I have bought her in doors and put her in a box with water. Any ideas as to what it could be and what I should do. Anxious...Karen

You never know, she could be ok and get over it. You're doing the right thing though and the vet will be able to say what's what.  Fingers crossed for you 

Ok I took her to the vet and she was put to sleep. We think she developed egg yolk peritonitis. Her temperature was off the scale. She had been laying soft shelled eggs for a while although with 8 chooks we were'nt sure which one was actually laying them, but it must have been her.She could have been treated but there was a high chance that it would happened again. She had a good diet so wasnt lacking anything.  We had a really odd egg too, it was tiny and when I cracked it there was no yolk in there.  We had been away for the weekend and a friend had kept an eye on the girlies, when we got back I was ill  with a nasty bug so in bed for a few days so not quite as vigilant as normal watching my girlies, so she could have been going downhill for a few days if we'd picked up on her condition  earlier........?

So sorry to hear that    I lost two girls to it and it's very upsetting as you do all you can but nothing works. One of mine got over it the first time only to get it again

It's just one of those things that hens suffer from so there was nothing you could do. You got treatment for her so don't beat yourself up over it

So sorry
