This simple idea has done such a great job I thought I’d share! My husband built this large wooden crate box for brooding the baby ducks/chickens. There’s a divider inside just for incubator/hatching before moving the chicks over to the nursery side. We put a light bulb near the top and also an electric brooder for the chicks to keep warm under. Plenty space in there for them to run around, feeding station etc and we put puppy training pads down for easy cleaning.(also has a lid when not in use).
We found them really easy to have in the house for the first 4 weeks but then they do start to wiff a bit after that. Because it’s so cold here in Ireland I daren't put them out too soon, even though we have a secure baby coop outdoors, it’s still cold most of the year so I have to suffer extra clean-outs to make sure they don’t stink up our house and wean them off the heat until week 6 when they’re much bigger and have their feathers so can stand going outside.
