We have two different groups of ducks on our farm: the better quality breeders and the ones that have made their way to our place in various different manners - quite a few of those by being rehomed to us. Chirp is in the second group.
Chirp was raised as a single lonely duckling during the winter of 2010. At the time, I didn't have any other ducklings his age and it being winter time, I couldn't find any anywhere around us. So, Chirp was brooded with a few guinea keets that were the same age as him. Not the most ideal situation, and not one I would ever recommend, either.
The problem is that Chirp doesn't think he's a duck. He has plenty of waterfowl company now, but he eschews them for our more land-locked fowl. He doesn't visit the pond with the other ducks, and in fact, I don't think I've ever seen him bathe in any of the kiddie pools, either. Instead, he spends his days nibbling on grass and hunting bugs with the chickens. Not a bad life at all.
And while almost all of our birds get along well together (although, I should mention that our turkeys, Jim Bob and Snoody, love to taunt the peacocks during breeding season, and we have just added a new type of bird that is not known for being sociable - more about them one day soon), it can be a little odd sometimes to see this one duck always mixed in with a bunch of chickens.
