So I have a black Australorp who lost oxygen at a week old our fault . He limped for a while and we thought she might end up a special needs chicken although she always seemed just fine. Then out of nowhere she regained use of the leg or so we thought and we figured all was good. This past week we had a really busy week with kids schedules so we hadn't done as much with the chickens like we normally do but I went out last night finally to check out everyone and I noticed this particular girl standing off to the side kind of funny. I picked her up and it appears to me that she lost the leg and pecked it off or the others did. She is now 1 legged and appears to be just fine. No one in her age group run seems to be picking on her (never has) and she is hobbling around just fine like it's no big deal. She's fat so I know she's been eating besides watching her. She is about 10 weeks old now. Will she be fine moving forward as she gets older? We seem to think so but I figured I'd ask some more seasoned chicken owners as we've only been at it for about 4 years.
