I wouldn't throw the eggs out, either. I've had hens get back on the wrong nest, I put em back on the right one and the eggs still hatch. Now if it's overnight or a whole day or the temperature dropped below freezing, I'd probably chunk em...(posted 9660 days ago)I've had two banny hens sit on the same nest. Last spring I let em do it just to see what would happen. Well, I guess they liked each other, cause once the chicks hatched out, they both tried to see who was going to be the best mother. Chicks would run from one momma to the next. When they roosted, or rather 'sat' for the night, the two little bannies would huddle together in a corner of their 'fledgling pen' (where I keep my free rangers for a couple of weeks, till they can maneuver over all the obstacles laying about)with all the chicks hiding somewhere amongst em. The satisfaction I got out of watching their comical antics was well worth any potential brooding risks that I feared beforehand.
