Our first try. We are using eggs from black sexlinks, some heavy red breed, RIRXColumbian. We candled the eggs and out of 14 eggs set, 8 were fertile. Some were moving in the egg! We are using this first try as a test run for some eggs we will buy. The father would be this guy: Bought him last year at auction. Not sure what breed (s) he is.. He is slightly smaller than a standard. We also have a bantam Golden Sebright. I am sure he is not the daddy, as he has a hard time reaching and getting the girls to stay still long enough to do the job.
