Yes, early on I had two go broody without rooster. I accidentally have a rooster now that was suppose to be a pullet order from my local Tractor Supply, AND they were to be ISA brown but I think they are RIR. Nice chickens though, but I wanted the high egg quantity of the ISA.
Now trying to...
when a rooster breeds with a hen, how long are her eggs considered fertilized??? Just the next egg she lays? Fertile all week? Just wondering in case I decide to raise a few chicks. And does a hen go broody randomly or does this increase when she lays fertilized eggs??
