At least 6 weeks old

The barred rocks are pullets. One of the brown ones, in the second picture, has a large comb for that age and may be a cockerel.

Also, they don't look right for brown Leghorns to me. They could be some type of Easter egger or other layer hybrid.

I agree, I think the second brown one is a welsummer

Pullets so far, but still too young. Update in a few weeks!

Here he or she is at 8 or so weeks!

Looks like a pullet to me.

Pullet! And looking more like a brown leghorn now

Doesn't look like a brown leghorn at all to me...

If a brown leghorn it would have white earlobes... I cant see them though under the feathers.
