i have a hen who has been spending hours in the nest box. i saw it yesterday and today. yesterday it was several hours and then she slept in it. today it has been the past 4ish hours. she is puffed up and makes a weird cry when i come by her. she is very calm, picking her up, checking her out. i thought maybe she is egg bound, we gave her a bath, and she ran back to the nesting box with nothing. i tried to stimulate the outside of the vent, and stuck my finger in there, but ive never done this before to know how far to go. i did not feel an egg, but not sure i went in enough. i was to my knuckle, then she seemed to get uncomfortable. thoughts? i had a chicken almost 2 weeks ago now with cocci, i treated the flock and no other symptoms from any chickens.
