The scale I have is like a deli style scale. It only calculates in pounds so I tried to convert it, and I did that horribly. I never claimed to be a math wiz, hehe. Thanks for pointing out my mistake. Maybe I can go buy a gram scale somewhere to make this easier. The converter I used said 1000 grams = 2 lbs. I found it online so maybe it isn't accurate.
Kathy, do you know how much they are supposed to gain in a day? I haven't been able to find anything definitive and my vet just says it depends on the duck. If he did gain just under 2%, is that adequate? (it was really only half a day of feeding though, he will get twice as much today).
Thanks!
