I am the person related to the ostrich breeders(in-laws).
They have 100+ birds on the farm in Virginia. Here is the only info they offer about the feathers on their site:
Natural color and dyed, body feathers tend to be more drab in color than do wing feathers. Prices range from $0.50 to $10.
Now, I plan to approach them about some type of arrangement where I'll sell their feathers for them. I don't think they have tapped the correct market yet. The feathers have to be going to waste. I'll let you all know if anything comes of it.
For now, if anyone wants to check out their site you can email me at firstname.lastname@example.org
and I'll forward you the site. I don't want to post the address because they are not exactly sponsors of the Forum. They ship ostrich patties, jerky, steaks, sausage, eggs and leather goods like wallets.
