Hoping for some help, I am a worried momma "hen".. my sweet girl is a 20ish week old Sex link, she has been sitting in her nesting box literally all day.. she came out once, this evening when I opened the gate to let them free range a bit, but came back to the coop after about 15-20 minutes, and right back in the nest box she goes. This is not normal for her, she has never before even got in there. I am only worried because she has never laid an egg before, has been in the box for basicaly 14-15 hours? I am nervous for her, hoping that there is not something really wrong with her? Is this normal? Could the egg be stuck at all? Sorry, this is my first flock and I am a nervous parent.
