Is she okay?
What are you feeding? It could be a niacin deficiency, has you checked for bumble foot? There are plenty of things you can do, are you on backyard chickens? You should sign up, I am Weeg on there, You can tag me, and Fuchsia to your thread if you sign up.
Aww cute. One of mine had a leg issue at that age. It outgrew the issue and I don't even know which bird it is now. No intervention required.
Been so busy with tree farm work closing out the season and then at least 6 inches of snow today.Sorry to hear that. Its hard to not know what happened so we can avoid it next time. Sometimes we find out. One year most my bottle lambs died. We couldnt figure out why. Next year I was mixing up lamb milk replacer and realized I had mixed it half strength the previous year. I dont think I've lost a bottle lamb since. I felt awful, but I still think its better to know. I hope your 2021 hatches are successful! Thank you for popping back in and updating!
