Yes!! Im behind in my grow outs because of it. I have 1 roo and 4 gals he was only mating 1!
I went through 4 batches of eggs only to have like 2/13 or 3/15 fertile!! Its taken about two more months but he is slowing mating all of them...I checked fertility yesterday and all eggs were growing. BUT my processing date is mid Sept so all the these birds hatching two months late Im afraid will be puny;(
