I currently have 18 birds all about 15 weeks old. 7 amberlink pullets, 5 golden comet pullets, 3 light brahma pullets, and 3 light brahma roosters. I've noticed the last few days, my roosters have started crowing and started getting "busy" with the hens. The interesting part though is they are only trying to mate with the amberlinks. They pay absolutly no attention to the brahma pullets, or the golden comets, but are constantly circling the amberlinks and mounting them any chance they get. Are amberlinks like the sluts of the barnyard or something? I'm thinking they are the "low-standards" breed. Does it mean they are closer to laying then the other breeds are? I'm still waiting for all these free eggs I keep hearing about.
