PA ends the day at noon. They do this so that hens that are on roost, ornesting, whatever you may call it,are not scared away from their babies and then refuse to return or lose them to predation when they are out of the area. It is what i have come accustomed to so I really couldn't care less anyways. I think ending at noon is actually a good thing.

*edited to better define "roost".. This is during the incubation period where the hens stay with the eggs and keep them warm, etc., until they hatch.(on the ground)Think of chickens and how they do it, its the same type thing.
