I have a 12 x 20 run that they can stay. Half covered half open with strings cross the top to deter the hocks. Works really well. However the whole purpose of getting these keets was to have tic and fly control in the horse pasture. If they can't get out to do they're job then it's all for...
Keeping them in a covered and kind of defeats the whole purpose of having them. I'm looking for ideas checking them while they are out free ranging. Thank you to those of you who gave the suggestions.
