I've never hatched eggs before, so this is new to me. My first batch is due to hatch this weekend. These babies are Cayuga/Pekin X. I have the incubator set up in my little boy's room, and the brooder will be in there, too. How long do these babies need to be in a brooder before they can be put in with the adults? Will the adults automatically accept them, or is there a proper way to introduce them? I let the adults out every day so that they can walk down to the creek and play all day. How old do ducklings need to be before they are allowed to go swim?
