So, I'm new to fowl. I did have a duck once... but... it was an indoor duck. (Don't ask... LOL) We have 4 ducklings now. 2 Rouen and 2 Pekin. We are planning on getting 6-8 Easter Eggers in a couple of months. We are getting ready to build our coop & run(s) now. But I'm running into some questions that I don't know the answer to. When we get our chicks, the ducks will be a couple months old, meaning they will be about 4 months old when we get the chicks into the coop/run. Should we build separate runs for the ducks and the chickens or could/should we house them together? We're planning on either 2 8x12' runs or 1 8x24' run depending. I'm planning on using a stock tank with a "deck" outside and a "stoop" on the inside. If we keep them in the same enclosure, should I go with a longer shallow stock tank with multiple water sources for the chickens? Thanks for all the info guys! I'm looking forward to hearing everybodys input and suggestions!
