i just have a homemade incubator with a thermostat, my humidity 1-18 is around 35 and day 18 on is about 70, so i dont know what to say. The food i feed them is just normal laying pellets.
I was just wondering if your hatch rate goes down if you are getting the eggs from older hens? I have done a couple hatches and they all turn out the same. Get put into lockdown fully developed and than never hatch.. air sac and everything looks right.. could that be weak hens?
