ok, These 6 seem to have figured out the higher roost. The run is 5X10. and a couple are now making a rather loud noise. There are free ranging chickens and 2 ducks in the yard. Do you think these are large enough to release 2 at a time? I just shot at a coyote tonight so I want to make sure they are large enough to get up high. I was thinking of adding a roost on top the run between the chicken run and the dog run the guineas are in. Do you think 6 feet up is high enough? There are apple trees and other large hardwoods in the area.
