I have 4 barred rock hens that should be laying right about now. They all come up on the stoop to visit with me when I let the dogs out & today "Red" was really curious about the open door. I just decided to let her in. She was acting weird, like she was looking for a safe place to lie down. I made a quick nest box out of a milk crate and she went right in and won't leave it. She's panting now and made funny noises when I got too close. Am I going to get my 1st egg right next to the fridge? That's convenient! Could it be something else that makes her want to be in a box inside? Like sickness? Thanks for any help!
