I am seriously considering getting one of these to use as a separation/health clinic/duckling run in my existing duck pen. I have 2 4 week old mallards I would love to be able to put outside with the other ducks, but I am very worried about the older teenaged ducks attacking them. I have already put them outside on nice weather days in a fenced in area, and the buffs seem very interested in bothering them. Any thoughts on how this will work in a pen that is about 14 ft by 8 ft, and covered? I thought too it could be used as a way to let them out more as well. I know that the hutch itself would not be great for say, leaving ducks in overnight because it wouldn't be that safe from predators, but it will be kept inside a predator proof pen most of the time. I thought for the low cost and the fact it needed little assembly, that this would be ideal for me, and I like the idea of a shelter against the wind or wetness if needed. Anyone ever had one of these? Anyone have any thoughts?
