Our Easter Eggers just started laying a few weeks ago (even though we got them May 30!!). I noticed last week that one Easter Egger (lowest on the pecking order) has stopped sleeping on the roost and started sleeping in the nesting box. It was about a week after she started laying eggs. She doesn't sit on the eggs after she lays them, and there is no egg under her at night when she wants to sleep in the nesting box. She appears healthy and is eating and drinking. She does tend to be by herself a lot more than the other chickens during the day, but she's always done that.
When it warms up we plan on changing the roosting bars... We don't have much head room and the chickens sometimes hit their heads when they jump up to roost. I'm thinking it might just be that she decided to sleep in the nesting box to avoid being picked on and hitting her head when jumping up since she's not on any eggs. I do shoo her out every night and she goes onto the roost and spends the rest of the night there. What should I do? Let her sleep there? or shoo her up on the roost?
