Today I noticed one of my nine month old pullets in the nest box when I did morning chores. She was still in the box a few hours later when went back in to check for any early eggs. She was still in the nest box. I didn't think anything of it because for the last week she's been spending more time in the box. I went back around noon (I like to visit my birds a lot) and she was still in the nest box. She was just sitting there puffed up and her eyes were glazed over. Two other pullets were trying to push her out to lay eggs while the other nest boxes remained empty. Silly girls. Anyway. Just before dark I went out to the coop again to see that everyone made it bed alright, and she was still there! I started hoping for a broody, but all of a sudden she got up and went the roost. The eggs she had been sitting on were hot. Is she getting ready to go broody? I don't want her to sit all day if she is going to roost at night because she'll starve and the eggs will die. Any thoughts? How can I encourage her to stay on the eggs at night if she is broody?
