I do some for my own consumption, but I do sell some locally. I`m in the process of expanding the process so maybe I can document that. I have no issues with birds what so ever. I never see the prawns until near harvest when I start checking for weight per prawn. The only time I can ever remember even seeing them in the pond without me trapping was at night a small amount coming shallow to feed on shoreline aquatics. I would say coons would be the biggest worry.
