Normally my hens sleep on the roost at night (for the last year since I've had them). Last night I found one of them in the nest box. She didn't move at all when I poked, prodded, and pet her. This is very unusual since normally my chickens are finicky and don't let me touch them at all. She kind of makes this high pitch low volume squeel/growl sound when I put my hand close to her. She doesn't peck at me unless I try and put my hand underneath her. If i put her back or head or anywhere else she doesn't move. She hasn't moved from the box this morning ever since I opened the pop door. Is she sick? Has she gone broody? When and where is she going to poop? Is she going to eat and drink water?
