I've been free lofting my birds for several weeks without any hawk attacks. I let the birds out early afternoon, and close the bobs in the evening after they have returned to the loft. I spent much of yesterday working in the flower beds and watching my birds having 'fun'. They were foraging on the lawn, taking baths, and FLYING. Pigeons are meant to fly! They are not meant to be caged continually. They were flying from loft to roof top in short bursts, swooping through the backyard, rising high into the sky and pinning out - every now and then one would decide to 'hawk' the kit. Who says birds don't have a sense of humor. They will retain their freedom, and I will enjoy their flights until the hawk attacks start once again. For now it's fun.
