I need help with my hen. I recently found out that one of my ladies is a fellow and has been mounting my females. One hen gets all loud and mean when she is on the nest. Before I knew that I had a rooster, I would just hold her head aside and take the egg. Should I leave her alone? Will she get off the nest or be on it all the time? How long do eggs take to hatch? The nesting box she likes is outside the coop, will she stay on it at night or go to bed as usual? How do I know that the eggs are fertile? Sorry so many questions. I never thought I would need to know this stuff as I had no intentions of having a rooster.
