My first hen, Idgie, just started laying a little over a week ago. I have several others that I think are getting really close. One other hen was checking out a nesting box and Idgie jumped in the nesting box with her and started growling very lightly. There's no egg in there, she used that box for her very first egg but hasn't been over there for any of the other eggs. She seems interested in looking for them, but she isn't sitting on a nest. Is she getting ready to go broody? Is it possible for her to be broody after only a week of laying? Will her growling at them prevent my other hens from laying in the nesting box if they are going to try to lay their first eggs?
