My husband came home with a half dozen baby chicks from the feed store a couple of weeks ago. We've had chickens for several years but not familiar with leghorns (which 3 of the chicks are). They've grown extremely fast in the past couple of weeks and have huge feet and legs. One of them more so than the others. Is this normal? Hubby thinks something is wrong with them. I think they are just fast growers. I've googled the breed and can't really find any information as to common characteristics of the chicks. Thanks so much!
