Four months ago I hatched 15 beautiful mutt chickens - large laying breed crosses. Dad was a Buff Orpington, and the moms were BO, RIR, Australorp, Lt. Brahma, etc. Anyway, I thought for a long time that I had a majority of pullets. In the last month or so, it has become evident that I had either 9 or 10 cockerels!!!! (I'm still not sure about one chicken - big comb, but blunt tail.) This is very disappointing, as this is my first new flock of chickens since we sold our last house and gave away our chickens two years ago. I have rehomed three roos, am keeping one, so have five or six more to rehome (or process). I thought I would get close to a 50% ratio, at least. What happened? It would have been great if it were the other way around. I have hatched chicks a few times in years past and don't ever remember a lopsided outcome like this. Is this a common occurrence for you other hatchers?
