Hi I am new to chickens this year. One of my hens (9 months old) went broody; so I got some fertilized eggs for her to sit. Now I have a few questions!! I have her setup in our small, enclosed greenhouse. I made a little nest and home for her. She has her own area, nest box, food and water all very close. 1) It has been cold here - 30s during the day. Lows in the 20s. Windy. Does she need heat? I have yet to put heat on them and our weather has gotten into the mid-teens this winter, but it doesn't stay that cold for long. 2) Will she eat on her own? She has yet to get up and poop. She's been in there for 2 days now. 3) I've read about the mites easily getting broody hens. Do I need to treat her with something? 4) Can I let her out? If she gets up, how long can the eggs be without her? 4) Do I need to do anything else for her???? I am new to this BYC, but LOVE the information on here. Thank you so much for your time and help!!
