We have 3 green parrots that like to roam openly in our house?
but now its feathures have grown and begun to take flight, this is dangurous as we have fans in our house.Kindly Seiling guide me as to how to cut their feathers at home.
Maybe not a bad idea to have an expert show you how do this at first.
