I have a Barred Rock and it is way plumper that the two white birds...all my flock is less than 3 weeks of age difference.
The one with the "waddles" has had those for a few weeks...I guess the other bird will catch up...she is the youngest and the first white bird is the oldest.
So y'all think they are both the same breed? Both Leghorns?
Definitely both leghorn pulletsthey are also the two that want to fly the most...very flighty, even with the wings clipped...
