Do these look like RIR?
I bought 2 dozen "fertile" eggs from a local. They were supposed to be rhode island reds. She did say that she also has white cornish rock hens.
This was my first time incubating eggs. 10 eggs were not fertile. 8 hatched just fine. The others did not hatch...
All but one had wing feathers of 2 lengths. I didn't notice any with black lines on their heads.
They're about 3 weeks old now, and 5 of them seem to be growing pretty large combs on their heads.
I'm afraid I've gotten mostly all cockerels.
I'm sure the white one is not rir.
I'm wondering if the others are mix breeds.
