My hens are all moulting for the first time and it's like they have all lost it. I've never experienced a moult either so this is new to me. It's like they can't find the nesting boxes and one of them has been making this low clucking sound sine it started. Is it stressful for them? I knew it took a toll on their ability to lay but this is crazy. I've been leaving eggs in the boxes to help remindevelop them but I can do that forever. Is this normal behavior?
