I have a barred rock roo and about 6 or 7 hens. Im wondering, is there a way to tell what hen each chicky came from.
I have 1 x RIR
1 X RIW
1 X ISA BROWN
1 X LIGHT SUSSEX.
Any ideas what they will look like or how to sex them?
If your rooster is pure bred (2 copies of the barring gene), all his offspring will be barred to some extent. A head spot may or may not be visible at hatch, depending on the color of the chick's down. No sex linkage here, you'll have to wait for comb size, etc.
From those breeds of hens, you're basically going to get a bunch of multi colored chicks. You've got the black from dad, and the mommas have a variety of red and white, so it's going to be a colorful hatch!
I think the only momma you'd dependably be able to identify is if a chick has white/pink skin, then it would be from the Sussex hen. The white skin tends to be dominant, and the other breeds you have have yellow skin.
They should be pretty birds, and since all these breeds are good dependable layers, the offspring should also be good layers. The cockerels will be big enough to make nice table birds if you're so inclined.
