did you candle them? you aware that shipped eggs are risky?
I live in the city so no roosters for me

All of my hatches have been mail order eggs.
Before this hatch I've done 5 hatches from ebay eggs from 10 sellers.
My worst hatch was 4 blue marans where 1 hatched and my best was 12 lavender orpingtons where I was sent 18 and 17 hatched!
On average I've had about a 60-75% hatch rate on ebay eggs.
So it is risky, but I've been pretty fortunate (knock on wood!)
I always buy eggs from a seller not too far from me (midwest to lower east coast). I read their feedback ahead of time and always let the eggs rest for a full 24 hours before they go in.
The marans are in here rocking around, but not seeing much for the Isbars yet. Hatch date is supposed to be Friday, but the marans seem anxcious to get out!
I did candle (With the marans it was pointless these eggs are so dark I couldn't see anything).
I got 6 Isbars, one I pulled out because it never started. 2 I'd say are pretty questionable, but didn't want to pull them out "just in case" since it's only my 6th hatch. Three of them were looking good at Day 15 so fingers crossed!!!!
