Oh breeding is super easy when you put mutts together though! /grin
I've just arranged to get a nice trio of bantam rocks in the fall. I'm so excited as this is the line I had before and they really did well for me. (Until raccoons eat them.) They bred and hatched so easily.
On the other hand, I had a superb line of OE blacks from a well known breeder. I couldn't get them to breed/lay/hatch for love nor money. Finally when I did, the same raccoon killed the 3 babies I got, one of which actually looked like a show bird. After months of trying to get anything. But then again I learned a lot from them. I always thought that you just give a guy two girls and voila!
But sometimes it's not easy. You kind of have to try something - give it a couple of weeks to a few weeks, then try something more. Then in your line's future, choose males for fertility to correct the issue and improve your line.
I do hope you get some good hatches and clutches though! For what reason are you breeding, may I ask? Show? Fun? Or?
Very exciting times!
