Sure:
Be very cautious - they steal hearts!
I have ten runners - I keep them in Little Fort Knox, as we have many predators in the area.
I have poured many hours and much love into this little flock, and it has given back many blessings - healthy, happy, social ducks, high energy but pretty calm over all.
I cannot speak for all runners, just mine.
They respond well to attention, though about half of them aren't exactly cuddly. They like to be near, but not be petted. The other half has three "huggers" who like handling, and two occasional "huggers." It's not too difficult to pick them up to check on them and medicate them when needed.
The most frequent health concern is bumblefoot, which I check closely for and treat early. We've had about a half dozen cases in a year. I treat with triple antibiotic ointment.
I use a splash catcher to reduce mess in the brooder/overnight accommodations. I have started switching over to an organic feed, which is not pellets, so I add water and have started using a deeper dish.
The "cute factor" helps with neighbors.
They love peas and lettuce.
They are my sweeties.
I've posted some pics here and there - you can search for them here. Many BYCers have runners, and there is some variety in ways they are managed and housed, and some are more upright (show quality) than others.
