My Buff Orpington was sitting on four eggs in an elevated nest box. I was able to move her to a metal dog crate before two hatched yesterday. There are two more she is sitting on. The only spot I could put the crate is on a shelf in the run. I’m unsure what to do not. She will need to come out but will she wait for the other two eggs to hatch? How long do I wait to see if the other eggs hatch? How will I know when she is ready to come out with the chicks so I can move the crate down? I do have food and water in the crate for Mom and babies. Hatching chicks is all new to me so I hope these questions aren’t dumb. I’m attaching photo of where I have the crate . Any response will be greatly appreciated.
