I went into the coop because I could only see 4 out of our 5 girls, and one was lying down, I THINK over some eggs, I saw a couple anyway, making low "puhpuhpuhpuh" sounds on and off, I didn't immediately think she was in danger cos I saw eggs so I thought she might be broody, but could this be something else? She puffs up whenever I come close and shifts a little too. Thanks
