I do not monitor my coop during the day. I caught her off the nest once last weekend because all the chickens were in an uproar as they were chasing her around and she was upset and shrieking. Other than that, I have no idea where she goes when! She is always sitting in the same nest box when I go out there in morning and evening. I have no idea if she will be good or bad or even how many eggs are under her. She is VERY upset when I look at her even and I haven't messed with her. I did find her beak covered in yolk and a broken egg next to her. I have a chicken that refuses to eat oyster shell and occasionally has a very weak shell and the egg breaks in the nest box. The shell I found was crazy thin, so I am not going to blame her for the snack.
How late at night should I try to get the eggs under her? Every time I go out at night, the chickens seem awake.
