Last year, I purchased 2 chicks - an Americauna & a Japanese Bantom. The Japanese Bantom turned out to be a roo. I introduced both to my small flock of 3 mature hens. The tiny roo submits to the mature hens & all of his considerable attention is focused on the Americauna. She laid 2 tiny blue-green eggs in the fall....& nothing since. She does WANT to lay - she goes to the nesting box & clucks & sits. But she produces nothing. She is not egg bound & is very healthy. Could the constant attention of the tiny roo be stressing her out? Could it be the cause of her not laying?
