Hi out there. We have a lovely broody hen that just will not give up. We placed three fertised eggs under her: two she destroyed and we had one lovely chick. We were away and the house sitter do not think to put a stone in the water dish and we lost it. So while away she had our friends put another egg under her. She has been sitting now for not only the first (21 days) but it has been 22 days and so far nothing. As she is so determine we are wondering if nothing comes of this egg should we even consider placing more eggs under her? It would mean another three weeks and I have never had this situation before. I feel she (and us) would love to have some chicks but is it good for her to sit this long?
