Squirrels ate my fava bean, and snow pea, seeds right away

Squirrels have always been a big problem where I live.
I have read that fava beans were good for soil, and could be planted in cooler weather.
I bought some seeds, planted them, and the squirrels dug them up and ate them right away.
I suppose I could sprout them indoors. But then, I am afraid the squirrels would eat them as soon they grew.
Similar story with snow peas.

I've heard some people have luck planting the seeds, or covering them up, with hot pepper spice.

I have similar problems with squirrels, mice, voles, rats, jays, crows, robins, etc.

But since I love peas and favas , I start mine inside in trays under lights, then transplant them once they get 6-8 inches tall. The peas and favas are transplanted into 40 gallon cloth pots and covered at first with row covers or netting. This  year I also transplanted some big seeded favas into a raised bed and clipped off the cotyledons before transplanting. This plan works fairly well, but it's a lot of work!

I wonder what would happen if you planted your peas and favas two inches deep, and then really stomped the soil down around them?

We have one advantage. The Grey squirrel is an introduced species, so there's no bag limit. I have a friend who hunts them ( he's a wild bird fanatic and squirrels are very hard on the nesting birds) and either skins and eats them, or feeds them to the local owls. A couple of years ago, he had an owl visit regularly that was raising 3 owlets. She'd call to him as if to say, "Come on, my babies are hungry, help out will you?"

I don't know what eats mine, but a layer of chicken wire over the soil until the first two true leaves form seems to stop them.

Chicken wire is probably the most reliable thing honestly. I had the same problem with peas, they'd vanish overnight. Started them in modules indoors and planted out once they had a few inches of growth, squirrels lost interest after that. Still had to cover the bed for the first week or so though.
