We have approximately 200 young blueberry bushes (ranging from recently planted to 5 years old).

Last year something ate all of the berries. Seemingly overnight all of the berries simply disappeared (including the majority that were under ripe or even green).

Any ideas on what would do this? Our best guess is turkeys but let me know if you have other ideas.

Any thoughts on how to deter turkeys (or other animals)? We had tried some basic mylar and bird eye devices last year, along with a few rubber toy snakes. It wasn't helpful. I am in the process of netting the more productive plants but with this many plants it isn't practical to use bird netting for everything.

Thanks!
