Went out to feed my girls this morning and one of my girls I got from the auction looked like her bum was swollen, red, and feathers around it looked icky. Anyone know what that's all about? I got her and her sisters from an auction and they were banged up pretty bad. Missing feathers, skinny, and act like they have never been allowed to forage. I am giving them layer feed, a little game bird feed (heard it Will help bulk them back up), oyster shell, and yesterday gave them DE dust and a bit of poultry probiotics in their water. They also get to free range all day and I give them tidbits from our leftover veggies. Anything else I can do to help them? I love my birds and want them to be healthy and happy.
