Ok I giving up. I got a class A trio last July and have set every egg since. Not one has been fertile. One hen is proven so I think its the roo. No more serama for me. I have another proven bantam roo ( about 1 1/2lb)and 4 small assorted hen. All 8 are going out to the garden. Mutts are better than nothing. I am very frustrated with trying for chicks. Has anyone else had a lazy roo.
