I have been noticing in my hatches that there seems to be a pattern emerging. All of my blue/green eggs always hatch great while a majority of the brown eggs I set either never develop, perish sometime during incubation, or hatch late. I'm starting to wonder if there is some genetic incompatibility going on with my rooster and those hens. Or if he just doesn't like them as much. Here is who I'm getting my eggs from:
3 Easter Eggers
Gold Lace Wyandotte
Of the hundred or so eggs I have incubated in the last couple months, I have gotten one Wyandotte chick, 7 barred rock chicks, and I don't believe any white rock chicks (she was also broody/raising chicks a good chunk of the time). All the rest are from the Easter Eggers.
I just did my first candle on a batch of 36 eggs and probably 5-8 (didn't count) of the brown ones were clear, 2/3 had rings/looked like they were early death, and I don't think more than 1 or 2 of the blue ones were clear.
Any studies out there show that some breeds are just not as compatible with each other? It would make sense that the Easter Eggers and Faverolles are more compatible because they have similar features and some common ancestors.
Or could my rooster just not be getting the job done? Some of my hatches weren't in the best conditions (old styro bator was on the fritz, I now have a new bator) so that could explain some of the deaths...
