The way you state that the Peas are gone in 2 days indicates to me that there is not enough plots to provide forage. I would guess that either larger plots or more smaller plots. On those Peas, use some kind of deterent to slow down their feeding until the Peas have a chance to grow. either the Plot Saver, or the simple plastic bag fence to deter them for a couple of weeks. This will give them time to establish some kind of root system to help them to survive. Somewhere on that 3000 acres there must be places for more plots. Sounds like there isn't enough food available.
