I have 3 copper black maran pullets that are 23 weeks old. Their combs have started to grow and I ave checked the gap between their pelvic bones, all 3 have a gap of 2 fingers. My question is how long is it until I should get eggs? Do their combs have to fully develop first? I also have 2 buff Orpington pullets and they only have a pelvic bone gap of 1 finger but they re a coupe of weeks younger than the marans. I feel like an expectant father!!!!
