My 5 barred rocks are approaching 3 weeks old. I purchased them all at the same time... from the feed store where they all arrived in the same box from the hatchery.... All of the girls are doing great... they all eat, drink and have different personalities. I do notice that one of the chicks doesn't seem to be growing or feathering out at the same rate as the other 4. She is a bit smaller. The others are getting fully feathered where the smaller one is just starting to get feathers... and has just a hint of tail feathers coming out, whereas the others have noticeable tail feathers. The small one's wings seem small too. Is this typical... the way people have different "body types".... maybe she'll catch up at some point... but just thought I'd ask if anyone has any insights. picts attached. Thanks.
