Yes — peas are good plant protein, and shelling the pods is excellent foraging work.
Keeper's noteFresh or thawed frozen, pods included. Pea-shelling is a gateway foraging skill for birds new to working for food.
Why peas is good for parrots
Green peas (garden, snap, and snow) are safe fresh or frozen-thawed, offering plant protein, fiber, and vitamin K. Unlike dry beans, fresh green peas don't need cooking. The pod is a puzzle box: birds quickly learn to unzip it for the prize inside.
How to serve it
Offer whole pods for foraging, or loose peas in chop.
