Thanks!
The dad is pretty good with them. We don't let him with the ducklings unless we are there and there is a lot of room. We divided our chicken coop in half with fencing so the mom and ducklings are on one side and the chickens and duck is on the other, so they all get to see each other. He's always sitting with them on the other side of the fence. The only problem is sometimes he'll want to mate so he tends to step on the ducklings when trying to do that, so we keep them separated unless we are there to intervene or the ducklings have space. We think the crooked beak is eating okay.. And we took the kayak out when we let the ducklings go to the pond to keep them along the shore. We haven't ever seen turtles but we aren't positive.
So the directions for the durvet vitamins say:
"Each scoop equals 5 gm. For dietary supplementation, mix one scoop per gallon of drinking water. Refresh water daily."
but it's for all livestock and poultry.. Do you think it needs to be even more diluted than that for ducklings..?
