Hi! I believe my ducklings are 3 weeks old. And the bigger one is a Blue Swedish based on internet views. The smaller is a domestic Mallard? Any confirmations? Oh and the nights are down to 60 degrees, days in 80’s soon to be 90’s is it too soon to be without heat lamp outside? I’ve had chickens for years, but ducks only when I was a child. Anyways they’re inside now, but when can they go outside. I live in Sacramento area. View attachment 1797373
