My Muscovy hen was sitting on a clutch of eggs for about 2 to 3 weeks but as of a few days ago she has stopped laying on the eggs. It is below freezing here and the formerly toasty eggs are cold. Worth noting, the Bronze Turkey Hen she shares a stall with also used to sit on the eggs and she stopped too. Questions: Has she abandoned the nest? If so, why would she abandon it? How long do I wait to remove the eggs? Can I prevent this from happening in the future? Thank You!!
