Awesome! I put eggs under 3 broodies this week alone. Just a little while ago, I put Sebright eggs under a bantam cochin hen, and she just settled right down on top of them. She'd been sitting on a ceramic egg for the past couple of days, so I figured I'd give her some real ones to sit on.
I'll take broodies over an incubator any day!
She does all the laying, all the turning, expelling bad eggs, raising her babies, exposing them to cocci, teaches them how to eat and drink and be chickens....all with no extra power bill!!
