Ok, i'm new to ducks. I got 8 muscovy ducklings, one week old, two days ago. Currently they are in a xl cat carrier, inside my chicken coop with 5 chicken hens. I bought duck starter, and have a small waterer, n small feeder. I cleaned out the carrier,last night, and gave them fresh water, as I plan on doing nightly. Question is, how long should I keep em seperated from the hens? The chicken hens are 3 yrs old, and they free range during daylight hours. I'm currently using a heat lamp for the ducklings. The coop is 6' x 6', with a 6' x 12' outdoor caged area. When can the ducklings freerange? Any suggestions would be greatly appreciated.
