So it looks like I'm getting 1/2 Black copper maran and 1/2 Blue copper maran hatching eggs, which is fine with me. Thanks for the tips! I'm flagging this for when I start them in the hatch next week. I'm looking forward to this one!
I am using egg cartons also, BTW, for the eggs I'm currently incubating and that seems to be working really well. I'm 10 days in and I lost 1 egg, but the other 9 are doing well. I had a furnace blowout/power issue over two days, so I'm thrilled I've got 9 still good.
