I like to trim the cocks feathers around his vent and off the side to make fertilization easier. Seems like my scissors were dull and the trim was ragged. When I went to my hair stylist, I was lamenting my problem and she said "Why don't you go to the beauty supply shop and buy some real scissors?"
At the beauty supply store I learned that the most common hair stylist scissors are 5.5 inches long and can cost several hundred dollars. For trimming my birds feathers she recommend this inexpensive pair at $9.99. I have never used scissors that worked this well! She warned me that they are so sharp that you must be very careful not to cut the bird!
