Hello! I am currently raising 17 chickens and 3 ducks. Right now, they are under a week old and are sharing a brooder. This is already becoming an issue because the ducks seem to grow at a tremendous rate. How big of a brooder would you suggest for 3 ducks? I want to get the ducks out of the chicken brooder within the next few days. Would you suggest putting an open bowl of water in the duck brooder for them to play in? Any suggestions would be super appreciated!
