Growing Challenge & It Doesn't end with the Peas!

So, the peas got et by a critter......
That's not really ok...I am a bit bitter about it, but figured hey...I didn't put down any of my mole be gone (which has seemed to help with groundhogs/woodchucks in the past). And it's a little too early for marigolds...
This weekend I scattered the castor oil infused corn husks (aka Mole-B-Gone) around the garden, planted some marigold seedlings and stared setting out my cruciferous plants which are another first for me. Broccoli and cauliflower I had started from seed and some left-over purple cabbage starts from my friend K.
I also started some chard, arugula and lettuce seeds.
I did this SUNDAY afternoon.
Yesterday I went to water them and EVERYTHING BUT THE PURPLE CABBAGE WAS GONE!
I am SO FRUSTRATED! How could the varmits have found these things so fast?!?!? Now I'm not sure whether it's a groundhog or a bunny that is managing to get past my defenses, and I 'm really afraid of setting out anything else.
I have more green cabbage and kholrabi starts that didn't make it into the garden on Sunday still in the greenhouse....not to mention all of my herb starts, tomatoes, peppers, eggplants ....
On a side note the garlic onions and shallots are doing just fine with no fence or protection whatsoever.
