I have a bunch of feral broody hens that keep turning up. (A phenomenon common to possessors of true broody stock.) They have a nest on top of a dog pen. I keep leaving the eggs there for bait. I let them get good and broody and catch them off of there at night. I have several clutches set now in individual pens. I'm thinking of giving one some turkey eggs. That should be entertaining.
One of my big hens just decided to set again. I'm going to give her 2 or 3 goose eggs. The "chicks" might outgrow her pretty fast though.
In regards to your earlier post about broodiness in males my Langshan cock will "babysit" the chicks on occasion. He's never sat on them, but does tidbit for them and stand over top of them to protect them from the non-broody hens. The Langshan hen that he came with is my best broody - 3 clutches last year, covers 18 eggs easily, takes any chicks you give her, etc. His daughter is the one getting the goose eggs.
