Well the walmart humidity was 5% lower than reality using the salt in a bag method....the outcome was 5 beautiful duck babies...but I think my mistake was that they hatched earlier than I expected, I was taking them out of the turner on day 23 and they already were pipping...so I should have had them out earlier...next time the ducks will do the incubating... I hope I have some breeding pairs from the five we hatched.
