Hello, this is my 1st spring with guineas and I have 1 who has spent the past 2 or 3 nights on the nest in the coop. I house guinea and chickens together and they all go in at night so I can close them up. 3 days ago she was around the nest alot throughout the day then on it that night. I have checked on her a few times during the day and she is off the nest, but then back on at night. Is she thinking about becoming broody?
