I have a few Buff Orps trying to go broody on me. How do I know if the eggs under them are fertilized? The roo that would have been the daddy (I just rehomed him on Friday) was only 8mo old and was hit or miss with the fertilization. If they aren't, what do I do for my broody hens if they are sitting on unfertilized eggs? I want them to be broody at some point, this just might not be the right time.
