We have two chickens and one rooster. Our rooster is a black/partridge Cochin and our girls are a white Sussex and a grey/blue silkie. We now have the pleasure of several eggs hatching. They are so far black with some having more fuzzy feet than others. Will it be easy to sex them I heard Sussex mixed with rir can be sex linked and so could silkies. I’ve never tried before. Thanks. Also any idea on colors. I’m not a chicken geneticist and have no idea on dominate or recessive genes in chickens I tried to read but....
