i have 3 male mallrd ducks.... and a couple questions from the more experienced... the were born in late april for 1 early may for 2... when do they learn to fly??? should they be flying already?? they arne't.. are they just lazy since food and water is easy? i would love to have females for them.... but right now can't afford to buy any... will they be okay on their own.. i've read some funny stories about boy ducks... lol.... and i wanted to put some fish in their little pool in the coop area.. will they eat the fish?? i was going to do this just to put some circulation in there and maybe help with the muck factor.. or should i just not worry about it and continue to just dunp the whole pool over every couple weeks and start fresh?
