I am still new to chickens, but I had all 5 of my hens go broody within a ten day period and only had 2 nesting boxes. I gave them a third box which no matter what I did they ignored. My hens shared the other two boxes and worked as a team. There was never a time that the eggs were left alone. Someone was always on one of the two nests. Sometimes three hens shared a nest along with the rooster who decided that he might as well help. The older hens were dominant but not aggressive towards the younger two hens. They are all sharing the parenting of the eleven chicks which hatched. Very cool and fun to watch. Good luck with your hen.
