I try to keep only pure breeds but my daughter got some Black Star hens for 4-H. Great birds, but no point in breeding them...until I just got up to my eyeballs in eggs. So, I had them in with my Cream Legbars because I knew that I could tell the eggs apart. Since I had so many eggs I decided that I may as well incubate some of the Black Star eggs and make green egg-laying "Easter Eggers". Well, the first batch went horribly because I had put the eggs in an old hatcher because my better hatcher was full and the resulting chicks hatched out very weak and a few chicks died right after hatching. In that mix were a buff colored chick, a buff chick with chipmunk stripes, and a black chick with a white dot on it's head that I thought was one of my Black Australorps (and accidentally sold it as such). I figured the Easter Eggers were the two buff chicks and figured the chipmunk stripes would differentiate between the male and female. So...with the second batch I got four of these slightly shaded buff chicks (one with a trace of chipmunk stripes) and two black chicks with definite white spots on the head. What gets confusing (not that I wouldn't be confused anyway) is that both breeds have Barred Rock genes but the Cream Legbar is auto-sexing but with the Black Star cross the barred pattern goes from mother to son. Anyway, I'm hoping some chicken genetics experts can help me with this one. There definitely is a clear sex-link going on here but I don't know if this is auto-sexing or just sex-link or who is who. On a side note, I sold all of my Black Stars but now I'm wondering if a sex-ling green egg layer wouldn't have been worth selling. I'm assuming that if I bread these chicks that the genetics would be all over the map and maybe also if I were to breed the daughters back to the father...but I really don't know. I was a bit confused at first because I hatched out both Black Australorps and Buff Orpingtons with these chicks and they sort of all look similar (except the one striped one that died that I thought might have been my only easter egger out of the batch. Thanks for any help!
