I voted bad idea- but only because the question is "to add ducks to the flock"
I vote that its a good idea to get ducks in general , especially if you loovvve one gallon projectile poops
,
but if you have an existing chicken flock it might be less stressful for everybird if the ducks are given
there own flock ( seperate coop / run ) instead of trying to put everyone together.
I have raised 3 day old ducklings and chicks together with no problem until... sexual maturity for male ducks. they sometimes become territorial to dominant chickens during mating season and if there is no female ducks , the males will try to mate the hens and they can get hurt/ drown.
feeding time can be exhausting and expensive if they are all together in the same area... Ducks need duck chow or waterfowl feed but which in my area is considerably more per pound price wise than chicken feed. Ducks are like Vacuums , they will suck down there own food (which should be provided in water or directly next to water) and then steal all the chickens food.. Mine can clear a 5 Gal chicken feeder... Chickens also love Duck Chow thats in water and like i said its 3x the Price of chicken feed.. We had to create a separate run area for feeding purposes..
I had 2 silkies drown in the ducks kiddie pool filled half way with water and buried on a tilt to have a shallow end
also purchased a group of ducklings from the farm store (straight run) and they were 100% male
I have always wanted to go to my local Counties Animal Control to adopt ducks that were seized and nursed back to health. . There are Ducks listed for adoption through rescues and county animal control on
