First of July Japanese/Cochin Banty hen went broody. Fine, I have a Japanese/Cochin Banty rooster, so I thought, no problem...I'll have some Banty cochin/japanese chicks. I have two RIRXDel sex linked hens that I was told would NOT be fertilized by the Banty Roo. Well, no chicks have hatched. I collected the eggs from my Broody Banty hen and ALL the eggs had bloody fetuses. So the Banty roo fertilized the RIRX Del hen's eggs too. Ick. What to do? I don't want to use incubator. Just let her keep sitting on the clutch to see if eggs hatch? There are several other nests, so I am not even sure why the RIR are laying eggs in the banty's nest. -- So I guess size doesn't matter...the banty roo has no trouble fertilizing the regular sized hens.
