Hi there, we have 3 ex-battery hens in our garden and yesterday I noticed one of them isn't moving around very well. She's eating and drinking ok - and she is pooping although it's quite green. She will wander around the garden a little but she looks uncomfortable and is all puffed up. I also noticed that she didn't jump up to her roost last night but instead slept at the bottom of the ladder. I added some cider vinegar in the water today but otherwise haven't tried anything. Very sad to see her like this . Any ideas? Many thanks in advance!
