Update on my hatch...not good news unfortunately.
So as per my original post, had LOTS of ebay eggs come in. Good news is, most of them were fertile and developing and no real issues with shipping.
Now the bad news....
I have a Farm Innovators incubator that has served me well the last year or so for hatching eggs. This year, my dear hubby built me a homemade incubator. I split up my hatching eggs between the two because the shipments arrived staggered. Towards lockdown, after candling all the eggs, i took out the infertile ones and consolidated everything into the Farm Innovators incubator.
Everything was going swell, had 4 eggs hatch, then 2 more. Then something bad happened...not sure exactly when but the temp stopped being regulated correctly in the incubator. As I said, had been working fine and was calibrated, etc. for several other hatches.
Had two egg babies die before getting out of the shell and none of the remaining 20+ eggs hatched.
Very very disappointing - lots of money wasted unfortunately. I did get 4 healthy baby chicks out of the hatch - two black silkies, a chick from one of my golden comet eggs, and a mixed chick from one of my hens - green egg from an easter egger. Baby chick is yellow with black spots and its feathers are coming in almost in a cuckoo pattern which makes no sense because I have zero birds like that

Anyway...that's my hatch story. Lessons learned for sure.
