This morning one of my RIR girls didn't come out to eat, so I thought she might be getting ready to lay. I left them alone until just a few minutes ago; when I went down to give them some more food and collect eggs. She again didn't come out. Going into the coop I collected the eggs I saw; she was in a corner quietly clucking. There was no puffying or attacking me as I checked and found an egg. However I went out putting the eggs safely outside the run, but returned into the coop to find her back in the corner. We don't have traditional nesting boxes which haven't been a problem for us. When my dad gets a chance I want to get some for my girls. However I'm worried about my baby girl in the corner because I'm not sure she's even eating or drinking. Is my RIR Broody?
