I have a young game that went broody 3 weeks ago. I decided since we really haven't had a really cold winter (Western NC) I would go ahead and give her some eggs. Due to her being small and it being winter I only gave her 4 eggs. Early this week marks 3 weeks and of course now we decide to have a colder winter than in the past few years. I have noticed the last few days she has pulled the straw in the nest box up all around her closer. Today she hasn't came off the nest at all. Yesterday I put a pet heat mat in a 5 gallon bucket on its side. Also I put lots of straw around the bucket. If she actually hatches will she use the heat mat to help keep the babies warm ? Also concerned about their water freezing if we have days below freezing all day. Anyone have anymore advice that might would help.
