We got them Easter weekend, they told us they were 2-3 wks old, both ducks and chicks. 3 chicks, 2 ducks. The chicks are feathering nicely. Still a tiny bit of fuzz but not much. Ducks are just starting to get feathers, mostly still fuzzy with a few bald patches. It's 37 degrees right now, pretty average for this time of year. The coop is 4x4, about, and has a 250 wat heat lamp. I'm ready to have these noisy stinky things out of my basement. Until we get the duck run built they will be in the same run as the chicks. For now, they will probably be locked in the coop with the chickens at night(to keep them safe and warm).
