So, I have two mating pairs sequestered in breeding pens. The roos are 1 year, 10 weeks; the hens are 1 year, 18 weeks. All are in good condition, and the hens have been laying faithfully. Problem is - when incubating, I'm getting nothing but clear eggs. The roos seem to be regularly mating, but I guess one member of both pairs is infertile. I find this hard to believe. My other chickens are fertile as hell, and I can hatch everything else on my farm no problem. Is there a propensity with Biels I am not aware of? I do seem to remember someone posting that a trim around the cloaca can help because of the abundance of feathers, but I'm looking for some suggestions from those who have had this wonderful breed longer than I.
