I have problems with mice and sweet peas - but they eat the shoots as soon as they germinate rather than scoff the seeds. You can normally see evidence of the decapitation - just a tiny little stem shorn level with the soil.
I cover them with propagator lids until they have germinated to keep the crittters out, amd then balance the trays on tall pots to baffle the meeses until ready to plant out. Once they are In the ground they seem tough enough to withstand the odd nibble.
