Mama is in a brooder box in our garage so they're super safe, but the box is wooden bottomed and has been lined with wood shavings. The nest is in a big metal bowl (really big around but about four inches from the ground to lip.) She has three chicks now and seven more eggs! Should we change the lining to something flatter? Should I do anything to allow them to get out of the nest or just leave mama alone to handle it? The chicks are popping around mama so they seem healthy and she seems pretty devoted. Any hints on how to make things easier for them?
