We have three young mallard ducklings. When we got them I thought that we would be able to free range them like our muscovys. They seem very skittish. I have this feeling that they are not going to go in at night when they can fly. They are free ranging right now, and have come back every night except once. I am afraid that when they start to truly fly they will not come back. Is this true? Next they are tiny. They have already taken off a little bit a couple times. My muscovys do not take off till they are about full grown. Is this true for mallards also? They are smaller than the call ducks I saw at the state fair. Are they going to get bigger? Since they are a wild duck will they only mate in pairs or will one male service several females? Thanks for any help you can offer.
