We have a hen who is broody in a nest box with one egg. We have candled it and we think it is developing fine. We believe at this point she is on day 16. This is our first time letting a hen raise a chick. It has been my son's project! So fun to see him watch this little hen. So the nest box is about 3 feet off of the ground in the coop. Should I make a lip on the edge? Move the hen and egg altogether? Also, she is in with 6 other hens. The rooster is no longer here. So I was wondering if I should make a cardboard area on the coop floor to give her her own space? Thanks in advance for any advice!!!
