Notice the lack of S in the title.
I know ducks and chickens can live together and share a space. My girls co-habitate a pen in the summer during our baby fox season and we have no issues.
I have 4 ducks and 1 chicken. There are now 2 more 6 week old chicks sharing the chicken house and they have the pen during the day. Introductions are slow, but they seem to work that way, so we take our time.
I do small numbers to brood (2 to 3 each time).
I know they do best in 3+ but have had 2 work well a couple of times.
The local feed store has no mins, I can buy 1 or I can buy 100 or their entire stock.
I don't want a lot of birds.
Has any body had any experience raising one chick and one duckling together? Then integrating them into an existing flock of ducks and chickens?
