It is perfectly normal for some first time breeders to lay nothing but 1 egg per clutch there first season around,I have some that are doing that now and I wouldn't worry at all as it is normal.
I have one that laid this morning and she only laid one, this is her first and my first time breeding. Should I be expecting another one? Or do they lay them two at a time with no time frame between them, like one right after the other? Thanks!
