I want to add a few more laying hens. Chicks take to long and the only place in central ohio that I've found them is charging $12 a 3-4 month old. I did find one lady selling 3 year olds for $3 each (lady says they're still laying). Worth while investment? Do they still have some laying days ahead? How often do they go broody? I know I could always just plop some eggs under her. I don't have a brooder so mama hen would need to do all the work.
