I had a call from a gal in Lady Lake who breeds peacocks and has feathers for sale. I actually purchased some from her and they were in great shape. The herls are great for toppings on streamers, fresh & saltwater, and of course make great bodies on nymphs such as the Prince Nymph.
From Gina: My feathers are from this year. When the birds naturally lost their feathers at molting time, I picked up the ones that looked decent. As for price, depends on how many you are looking for. For example, if you wanted to purchase between 1 and 30 feathers, I charge .50 cents a piece. Anything over 30 feathers the price begins to go down a bit.
