Someone's dog is eating her hens, so she is giving them to me. 2 RIR and 2 Barred Rock. If I put them with my Lavender Orpington roo, what colours do you think I will get from the RIR and from the Barred Rocks? I know absolutely nothing about chicken genetics (yes I have seen the chicken calculator and can't even begin to understand it). Thank you for any insight.
Getting some new hens---What will they give me?
First I will say that Lavender is a recessive gene, so when a Lavender bird is bred to a non-Lavender, they will breed like a solid black. All chicks produced will be 'split' for Lavender, but their color will be mostly black (you may get some with 'leakage' from the RIR).
Barred hens, when bred to a non-barred, non-white rooster, will produce black sexlinks. Female chicks will be black. Male chicks will have a white spot on the back of the head, indicating the presence of the barring gene. A barred hen can only pass that barring gene to her male chicks.
There will be no sexlinking with the RIR hens. They lack the necessary genes.
Basically, if you hatch their eggs, you will have lots of black chicks. Any chicks with barring will be male, but unless you keep track of which eggs came from which hen, you can't be sure of which chicks are black sexlink pullets, and which are un-sexable black RIR mixes. You'll have to wait and see which all blacks are pullets
