I set 26 eggs on the 8th, 10 Ameraucanas from the mail, 8 pure Rose comb red dorkings I bred, and 8 eggs from my Buckeye roo crossed with a wyanndotte and chantecler hens. They all showed the spider developing except those by the Buckeye roo. I checked the eggs laid by these hens both before and after I collected the ones for the inci, and they all had the telltale bullseye, they are also his favorite hens and have been over bred if anything. Any ideas why these aren't developing? Do buckeyes take longer?
