I know you can keep ducks and chickens together but is there anything to be warned about? Do they eat the same feed? Do I need to have a little duck pool IN the run because we are free ranging our chickens and would with ducks. But some days we don’t free range if there was a predator or we were too busy! And how big of a pool do we need? And where would be the best place to get ducklings! Are drakes like roosters? Do they crow? I’ve done some research but I want more than one source and I think this would be a good place. Any other info would be appreciated!
