So today I went out to do the evening feed + water, lo and behold, those 2 crazy Old Lady Moms had the 3 babies out swimming in a mud puddle. ... Right alongside the rest of the flock. Now today in MI has been nice, 52' and relatively warm. But I thought ducklings needed 90' brooding temps. I'm confused but I did get the babies for the moms to raise. So when I penned everyone up to eat, I noticed that the moms took the babies to the outdoor house and ran everybody else out. So does this mean they are just moving outside? Or should I force them in and lock the door do they have to stay in? One other consideration, since nights still fall below freezing, I'm still using the heated 5gal bucket for water for the adults. I'm worried about the babies near that (drowning)-- even if I put a brick in the bucket, I dont think that would be enough for a week old duckling. What would you do here?
