Cornish giant nesting?!

Who knew?!? So last year I bought 10 chicks from a local small farm. These chicks were the old fashion pre-1979 poultry standards Cornish giants.

These are not quite the same as today's hatchery Cornishs that go from egg to butcher in 12 weeks... the old genetics take a little longer to grow out, but they're almost heritage birds, less leg and heart problems (in theory) and still tasty. The plan was to breed the hens, incubate a couple batches of their eggs every year and raise them for our freezer. Unfortunately we lost one chick fairly early. Then they grew up, and we wound up with 7 roosters and 2 hens. Luck of the draw I guess! By the end of last fall, my dreams of this plan working for our self-sustaining meat bird factory diminished. We had 2 of the roosters have heart attacks when they hit puberty. Then an animal got to one of the hens and another rooster :(
We did butcher one of the roosters, leaving us with 3 giants. 2 roosters- who terrorize the dogs and our children, but do a pretty good job of protecting their harem. The lonely Cornish hen has been happily hanging out with her sister wives. She started laying eggs after her winter break, about 3 weeks ago. I figured I'd start saving her eggs to incubate, and had 7 set aside when we noticed she was always in the nesting box when we were collecting eggs. Could she be broody?? That'd be weird! Cornish hens aren't supposed to have that maternal instinct.. yet she has stopped laying her own eggs again and was feircly trying to defend her right to sit on the eggs of the orhers. So I figured why not give it a try and give her her own eggs back. That was almost 2 weeks ago and she's still nestling!! Way to go momma! I'm hoping and praying we'll have little white fluffy but nuggets chirping around the henhouse next week :)
