After dark tonight I found a baby chick in a nest that must have hatched after the mother left with the others, she has not returned to the nest and since our chickens are free range and we have 4 acres and its dark I could not find her. We have around 30 chickens and 2 hens have babies. I don't know which one it belongs to. I have it in a box with some grass and straw, I managed to use an eye dropper to give it a drink, it peed and pooped, at least what I think was poop. It is chirping for its mother so I've got at least 5 hours before daylight and I don't know what to do.
