Erik and Chi,
I agree with Chi. This raises a question for me as well. I am considering imprinting and tame hacking a coops next year. I live on a hill and there is a resident pair of RTH that have lived here longer than I, 15+ yrs. 5 years ago I had a passage RTH and during mating and nesting season the pair routinely harassed him in his weathering yard. Ultimately they got use to him being around. Is hacking in the territory of resident birds a serious concern?
