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.
