I recently did two hatches before the one I'm about to get in to. None of the eggs hatched in the first try and only one hatched in the second try, but I accidentally stepped on the baby (a very traumatic moment for me) earlier this week. Both of these times, I was using a still air incubator, but this time I'm using a forced air incubator. I'd be heartbroken if nothing made it to hatch day this time, but the person I borrowed the forced air incubator from has never hatched call ducks and knows nothing about them. Does the temperature and humidity need to be different for calls in a forced air bator? Is there anything at all I should know about the incubation process before I put the eggs in the incubator? (Just as a side note, I'm also using an egg turner for the first time)
Call ducks are among the more challenging poultry to hatch. I would ask a breeder specifically of call ducks for their advice. Much info can be found on the ABA website which includes bantam ducks. And breeders by the dozens can be found in their yearbook which is full of information and well worth the money.
We had absolutely no problems hatching calls in a Still Air incubator, we hatched them the same as any duck we would hatch.
