Ok I'm jealous my lavender Orpington roo is either too young or infertile! He'll be 9 months 1-9-16. Not interested in his girls at all. None of his eggs started this time.
Aren't Orpingtons generally late to mature and lay? If he's not even trying yet I wouldn't worry about him being infertile. I love this time of year because after the solstice, as the days get longer, the young birds come into maturity and really start mating and laying.
