My Welsummer's been broody for probably going on 2 months now. At first I had to kick her off the nest a couple times a day (we don't have fertile eggs, so she was wasting her time), but then after a few weeks she started leaving her chosen nest box and roaming around with the others of her own volition, so I thought maybe she was finally snapping out of it. But she still prefers to sit on the nest, is still acting strangely and looking more and more scraggly. So I'm thinking for her sake it might be best to intervene. We're considering getting some new chickens anyway, so what I'm wondering is if we got some fertile eggs for her to sit on and hatch, once they hatched, would she be able to move on and either raise them herself, or at least have something click that she's accomplished her task and get back to normal? Worth a shot at least? And, is it harmful for hens to remain broody for so long?
