I also started some eggs on the 5th - I had 6 lavender ameraucana and 6 wheaten marans shipped. All 6 of the ameraucana eggs are looking good - the marans eggs I really can't make anything out.
I started a bunch of my own EE eggs at the same time (maybe about 2 dozen?) - they were old, and had been refrigerated, so I didn't expect too much, but none developed

But I can always try again.
I put three silkie eggs into the bator on the 8th - my silkie laid her first eggs and I figured I'd give them a shot! Two are definitely developing, one has a blood ring, I think, but I'm going to give it a few more days to be sure. They should be black, possibly showgirls. I am excited, they'll be my first homegrown and hatched chicks!
