It seems like it might be normal for the breed. I thought I might want to start breeding Ameraucanas and bought a batch of B/B/S hatching eggs from a breeder. They hatched around the end of March or very beginning of April last year. I got 2 or 3 eggs out of the six hens in October and nothing...
Very excited that 19:24 of my B/B/S Ameraucana and black copper Marans eggs hatched! Looks like I ended up with 5 BCMs, 2 blue Ameraucanas and the rest splash. I need to take new pics....chicks are about 3 weeks old now.
