I got 4 new pullets/hens tonight. 1 EE - Previous owner called her A-something but comparing her to the EE's on this site, I think that is what she is. 1 Black Australorp 1 Buff Orpington 1 Welsummer The previous owner was really nice. She had 40+ chickens and was downsizing. Her coop was nice. Some of her birds had bare backs. One had a curled toe and another had big blister-looking thing on her foot. Overall, they looked ok though. I made my selections and brought them home. They are in isolation in my barn. Edited to add: I did NOT bring home the curled toe or blister foot chicken. I did get a bare back and a bare belly. One needed a bath. She messed her crate. I put petroleum jelly on all the legs and dusted under wings and around vents with Sevin. I sprinkled Diatomaceous Earth and Sevin around their pen. I plan to keep these four in isolation for 30 days. Do I need to do anything else? I was thinking maybe apple cider vinegar in the water or safeguard them? I didn't see any parasites, however I do not want my other chickens to get sick. Is 30 days too long or long enough?
