Hi there, I'm totally new at this so I have no idea what I'm dealing with. I've looked at a few posts about a dirty bum and I think I might have a bit of a problem. I got 2 hens 4 days ago from a guy who got them from a battery farm. He had been free-ranging them for 4 mos, but didn't really take care of them. Didn't treat them for any parasites/diseases etc. So one of them started laying eggs 2 days ago, but she is also the one with a really really dirty bum. I didn't think anything of that until I started reading some posts on here. So I got her in a tub of warm water and soaked/splashed soapy warm water on her for about 10 mins. I pretty much got most of the poo off, but there is still some caked on there. Should I try and get that off?? I uploaded some pictures which aren't the best because she kept moving. Any advice or suggestions would be really appreciated!!!
