Egg pusher! I'm thinking about it. I have a small coop that I've used as a brooder for chicks, but I mostly hatch chickens under a broody. It's just sitting empty, but the downside is there is very little light in the coop unless the door to the run is open.
I'll look at the Cage build when I have a chance.
Do they need nestboxes? Can you raise them with chicks? How long do they need heat for after hatching? (since they lay in 6 ish weeks, I'm assuming they feather in really quickly) Can they handle cold/heat well? Would they go in on their own at night, if they have a run? (that is the ONLY reason I do not have ducks, we are in critterville) I had turkeys once and they never went inside, so they got picked off and I had to give the last 2 away.
I don't think they would go in on their own at night. When I raised quail, the door to their pen was left open one night. The next morning Moose helped me gather them up. I was certain we had got them all, Moose kept telling me no, they weren't all there. I counted again, decided they were all there, Moose said no, I took him inside with me. We were sitting in my office, Moose started barking, I looked out and there was a quail out in the yard. We went out and got him, Moose was happy, I swear he muttered under his breath, "I told you so", I never doubted Moose again.
