Our hen, Hennifer, has been broody for well over a month. I heard that they usually went broody for only 21 days. Is it normal for them to stay broody this long. Or is there some other problem I'm not seeing. She seems to be healthy, and she comes out about once a day to get food or water then heads straight back to her nest. No visible weightless that I can see. Our other hens, Chickoletta, and Ming-Ming are out and about as usual. They roam around our yard basically 24/7. with plenty to do, So why isn't Hennifer out there with them? P.S Ive tried taking Hennifer out of her nest,which is sometimes a struggle because she doesn't want to leave the nest, and placing her on the other side of the yard. She will stay out for a little while, maybe 20-30 minutes. Then she heads back to her nest as normal. P.S Again: We were wondering if she is broody then should we get some fertilized eggs from our neighbor and allow her to hatch them? Thankyou.
