I am a first timer with using a broody. Wynonna is doing an excellent job taking care of her 4 Eggs! Even in this bitter cold winter in Wisconsin!!! I had an issue with other hens stealing her eggs and not sitting on them so I had to separate Wynonna and her eggs into her own private Rubbermaid Tote. She is still in the coop though. I take her out "potty" twice a day, she is not able to exit on her own. She dust bathes and stretches her legs and socializes and then I place her back in her tote and she is content. I have food and water in with her and she has not made any poops in her nest.... SO my question is.... today is day 18 and I am wondering if its still OK to take her off her nest? How about after the chicks are hatched? I have been bringing down a gallon ziplock bag of hot water to place over her eggs while she has her reprieve. Temps have warmed up to the 30's. The coop itself is totally insulated. Also...... Once the babies hatch how many days should I wait to let her introduce her and them to the rest of the flock. I was planning on keeping her with the flock. Thanks much! I am learning a lot and enjoying my chickens!!!
