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.
After this is one of my bigger hens went broody in the middle of winter I wouldn't be afraid to give her eggs and let her hatch them. BTW I'm in the foothills just below Boone so your probably a little colder than me.
