with having more experience with bantam hens I don't know what to expect with my standard cochin. she has already layed 13 eggs but does not seem to be interested in going broody. one problem might be that the roo is a MF d'uccle bearded bantam because my standard roo was killed by a predator, and he took over his girls. this might not even be possible and the eggs might not be fertile, thus causing her to ignore them. i have witnessed him trying to breed my girls but don't know if any good was done. i know that these will be mixed breed but i still think that they will be beautiful birds, thats if the miracle even does happen. My bantam hen usually goes broody after about 10. Right now she is brooding 9. just wondering?
