Left behind- the chicks

So I have 2 hens that we allowed to go broody. 4 chicks have hatched a couple days ago and today they have ventured out of the coop. The issue it that there are about 15 eggs left in the nesting box at various stages of development and the hens have been off all day. I just went in to clear the nest and I found one egg had pipped and is peeping. I don’t know how long ago it pipped and I don’t have an incubator so it is currently in my bra😅 I’m not sure at this point what to do with the pipped egg or the leftover eggs so any advice is greatly appreciated!
