They won't hate each other, its good for them to have a companion. Yes they can die from loneliness, however, a stuffed animal will produce the same results. LOL... but don't be surprise when its time for the duck to go outside the chickens will want to be with her. Yes, the chickens will hang out with her even while she's swimming so becareful that the chickens don't attempt to try and swim with her. Remember the duck is all they will know and will follow her, since ducks grow up faster then chickens they will think hummmm check out our mom... She looks like she's having a ball.LOL
Ive had it happen several times with my chicks, some not so lucky but some I was able to get out of the pool in time.
Oh my!
I did not think of that. I will watch them carefully when they are ready to go outside. Sounds so cute too.
My east indies laid their first egg. I cant believe that huge egg came from one of those little ducks. I do know they take 28 days to hatch. Do you know anything about hatching them? I imagine your lazy method would work for them too. This is so exciting! Harching my own eggs! And no more dealing with dammaged air sacks.

Also do you leave one of the vent holes open in your incubater? Mine does not have a fan.
