I have freedom rangers (for the first time) right now, so I appreciate the question about breeding.
Had to cull a 3.5 week old freedom ranger chick today. It had one leg that was weird. Last week, I noticed that one leg was pink and one was yellow. I looked closely, but all I coud see was a tiny scratch. It must have gotten infected or something? The skin got pinker and started peeling off. I took the chick inside and gave it a foot soak and cleaned off the leg, and the dead skin peeled off. I thought the water was too warm, but the water was only slightly warmer than room temperature. I slathered some bacitracin ointment on it. I did that two more times, but it progressively got worse. This morning the chick was limping very slowly and the skin looked very thick and weird, almost like pictures I've seen of scaly leg mites that have been there for a long time. Only the one leg was affected, no other part of the chick. It never felt hot to the touch or oozed anything, but the nails looked funny too. I wonder if it was something viral or other systemic issue. I'm still a newbie at the meat birds, so I didn't know if could feed the poor thing antibiotics to try to treat or not, and then still be able to use the meat later. No other chicks were showing signs of anything, and are lively and happy. I wanted to be sure that if it was viral, that other birds weren't exposed any longer. :-/
