OK, we are going to give it a try to hatch some eggs. Live in Ohio so won't start this project till May. Do all eggs take the same time to hatch? Would it be best to separate the broody hens in their own private quarters? Can I have more than one hen in the same area if they are both broody? This will be our first attempt and have only had chickens for a year. How do you check to make sure the eggs are fertile?
