Ok...I just got the chicken thing down...now I have adopted 2- 2or3 week old mallard ducklings. The man at the feed store said that they can eat the medicated chick feed because they are past the age where it can hurt them. I read around on here and everywhere says Non-medicated only. Ok..I have raised ducks before and always bought unmedicated, but they kinda showed up as I was walking out to the car with my 50# bag of medicated chick starter. I really didn't want to have to buy different food, but I will if it is necissary. I asked them there and they said it is fine. I don't want to hurt the babies....so I haven't given them anything yet...they were dropped off ehind the building to fend for themselves at all of 2 or 3 weeks..1 has a few feathers near the wings and both have tail feathers starting to pop out.
