Hello, I have been doing a lot of research on chickens. I never had birds as a pet and currently have two shelter cats. I have learned a lot and have decided to adopt three ISA Browns ex-battery caged hens in July. I am having a chicken tractor built for me from a guy in San Diego. Found Bird vet in my area and learning chickens come with expensive stuff! So what I was wondering as I noticed when I volunteered at a chicken adoption event recently they are pretty dirty. So how soon after can I give them a bath. Don't want to shock or traumatize them since they are already traumatized to begin with but don't want them starting their new life with dirty bottoms!
