I got some nice brown eggs from the farmer's market to try hatching, and when i asked what breed of chicken the eggs were from, they told me Light Brahma crossed with Red Rock. I understand a Red Rock is actually a hybrid egg layer from either a RIR or NHR roo crossed with a Barred Rock. So I was wondering what the chicks would look potentially like under each instance, as I am not sure if they meant a) Light Brahma rooster crossed with a Red Rock hen to make my fertilized eggs, or B)The hens that paid the eggs were Light Brahma crossed with Red Rock, and then the roo would be unknown. But they were fertilized for sure...just have to wait 2 more weeks to find out what I get if anything hatched. What colour feathers will I get? Will I get a mixture? Some red, some white, some black? Also, is there a chance I will get feather-sexable or anything that I can tell male/female at a young age? I tried plugging it into the chicken genetic calculator but got kind of confused. Thank you so much for any help.
