Pros: Prolific layers, flightless, excellent foragers, easy for beginners
Cons: Easily excitable, non-maternal.
I got my first Indian Runners during the summer of 2012. I raised one as a duckling, and the other two were raised with the flock my friend owned. The first one I raised unfortunately died due to health defects. But the other two birds absolutely thrive and are healthy as can be.
My two girls are absolutely unsocialized and that has made handling them tricky. However despite this the birds are easily herded and can be brought into the coop without too much trouble if they don't adhere to the usual schedule.
I feed them on a daily basis, however they don't need to be fed that often as they enjoy and almost prefer foraging. Some days they will ignore the feed I leave for them altogether. They adore water, as all ducks do, and typically spend a majority of their time in the pond.
Being flightless, we haven't been too concerned about them wandering off. The fence we use to keep them in the yard is between two or three feet tall.
My friends flock lays eggs on a daily basis, and we are quite excited for ours to start this spring! Even when they lay fertile eggs, they are too flighty, excitable or uninterested to brood. So having a surrogate brooder or an incubator is typically necessary if you intend on breeding.
