Hello everyone, I live 20 miles north of green bay Wisconsin. I've read many forums over the last year from back yard chickens and finally decided to become a member. Recently we decided to hatch some of our own chick's from our flock. I've done a lot of reading on arcing chick's and can't find much on crossing our breeds. We have a black copper Maran roster 8 barred plymouth rocks, 3 buff orpingtons, and 4 black australorps. My questions are: 1- does the sex link trait work with the orps? (I know it does with the rocks, being most info I've read use the barred plymouth rock as the hen in examples, however none I've read use the black cooper Maran, mostly the Rhode Island red) 2. Is there a way too determine sec by traits in the black austalorps eggs using the black cooper Maran? 3. Most talk about the white spot on the head being the cockerele, I'll try and post pics of my chick's, but these are bigger than just spots. All chick's so far have all the same characteristics between may would be the males and the females. Males white on head with lighter beaks, females all black with black beaks. (Hope i didn't screw that up. We had 2 birds that came out of lighter shells and smaller that i think are the orpington's ends, the chick's were light tan with a yellowish tint, but both died within 12 hours of hatch. Weak from the start. Or would those be from the australorps? It's crazy all 10 survivors seem to all have same characteristics even though the different breeds of hens.
