It's day #8 for the guinea eggs of temperatures of 100.5 in a still-air foam incubator. I just put the banty eggs in yesterday, since guineas are 28 days verses chickens' 21. I candled the guinea eggs on the 20th of May. Of my 23 eggs, three were unfertile; the rest are developing at an excellent rate.e The bantam eggs' dad is an Bearded D'uccle; Mom's a Brahama banty. I put twelve of those in. I'll keep everyone posted!
