2 weeks ago I bought 8 chicks from TSC and was ecstatic that I was able to get 2 Leghorns. They were the same size when I got them but now one is very large, her crop is almost always full. Its not hard nor too soft and I have seen it empty a few times. She waddles quite a bit and her feathers are very slow coming in compared to the rest of the chicks. She mostly just sits in the corner of the brooder, but is really friendly she will come when we tap at the side of the brooder.
Should I be worried or is this seem like a normal thing? This is my second time raising chicks from TSC, last year we purchased 6 and they all had no problem. Just looking to see if anyone else has had this happen and if so how did it turn out. Thanks
