So none of the replacement eggs are developing DAY 4, I will wait until DAY 7 to toss. I have given up on shipped eggs.

Imari is now also showing slipped wing on top of the single comb. He is a little sweetie, but I do not think I will use him for breeding. Even though I hatched him from a breeder's eggs, I suspect he is hatchery stock.
Only one left is my paint egg (out of 59 shipped eggs total) here day 13, looking good. Hope it is a paint or dominant white and not just plain old black.
Of my own birds, I am still not getting any development from two of the silkie girls. I honestly do not think my cockerel is mating with them. Even I separated them for 3 weeks, nothing.
Zelda (the white hen) just started laying. I have seen him mate with her. She is one of his favorites, so I expect her eggs will be fertile again. Luckily, most people around here seem to prefer the white silkies.
So I must say this has been a good lesson for me, that I can not control everything, and have to let it go. Still disheartening, though.
