Blueberries are easy to net, get some 1/2" PVC pipe, some 3 ft rebar pieces, and make a hoop frame, then put netting over the frame. (I like americannettings.com)

Birds can vary their diet depending on the time of year, if your gold raspberries ripen after summer, the birds may be on to other foods.

Black raspberries display their fruit very prominently.

thanks for the reply about black raspberries being very prominently. I plan on having 5 acres in the future (probably zone 8 in Georgia) for planting berries so I'm trying out lots of different types.

Do the big blueberry farmers us bird netting on say 1 acre?

Any good red raspberries for zone 7-8 that hide there fruit under the leaves?
