How long will hen stay on the nest once some of her 9 eggs have hatched?

If you can put a feeder/waterer near them, the chicks will venture out and eat/drink, or mom will show them, then return to her nest.

Our nests were high up, and they'll try jumping even. I had moved the mothers, eggs, and chicks to a nestbox I made out of a cardboard box on the floor and put the feeder/waterer right in front of it.

Thank you, that really helped. We'll put water in mini-drinkers out in front of the nest tomorrow morning and keep our fingers crossed for the remaining eggs. Today is Day 22, so maybe everyone is just later than usual. Sadly, patience is not my virtue
