I have a Buff Orpington hen who is just over a year old. She started being broody about a week and a half ago and is not eating or drinking. She won't eat from my hand, and I have to drip water over her beak to get her to drink. Her comb and wattle are incredibly pale, but she just won't get off her eggs at all. She has only pooped twice since she went broody. Should I be concerned or is this normal?
