I have a hen that went broody and I let her keep 4 eggs to try and hatch. It’s 8 days in and I checked last night with a flashlight and looks like all 4 of them are developing. I hear a lot of people let the hen raise them within the flock. Right now the nest box is 5 inches off the ground. The eggs are marked and the other 4 hens still lay in that box. Do I wait for them to hatch then move them to the ground area or should I do it a few days before. I was thinking of building a cage area with the front open so the hen can still mingle with the flock. Any ideas this is my first time hatching.
