Delaware? White Leghorn? something else?

[A.T. Hagan]

#1 is a Rhode Island Red. #2 is a White Leghorn. Both appear to be approaching point of lay.

The barred one I believe to be a Barred Rock, but could possibly be a Dominique if it has a rose comb.

I have some of those white chickens. I got them from a guy that sold them to me as white leghorns. The white chicken in the picture if it is a leghorn will lay a white egg. If it does not lay a white egg it is a white rock. Sometimes it is not easy for me to always tell a white leghorn from other white chickens but the egg color always shows me.

Not a White Rock. No way. The White Rock is heavy and shaped nothing like the leghorn-ish bird in the photo.

The white bird is a leghorn or some type of leghorn-based layer. That light body is made to lay tons of eggs on not much food. Different hatcheries offer their own layer and they're not always pure leghorn but based on them anyway.
