Oh yeah, unless you have a fairly sure market for them, or livestock to feed them to, you'll probably never need more than 1 each, of the following plants: zucchini, cucumbers, summer squash of any kind.
I picked enough squash and cucumbers yesterday to fill both sides of my kitchen sink. I have 2 hills of squash, and ONE cucumber plant. Fortunately, I have both chickens and pigs to eat the surplus.
If you have way too many squash, cukes, or zukes, be prepared for your friends and neighbors to begin hiding when they see you coming. If they garden, they'll no doubt have excess of their own!
Chickens and pigs don't like raw squash. But I found I could (in the evening, before I go to bed) fill a big enamel pot with chopped up yellow crookneck, put a little water in the bottom, maybe an inch or so, and bring to a simmer. Meanwhile, heat the oven to 450F, put a lid on the pot, stick it in the oven, turn the oven OFF, and go to bed. In the morning, the squash will have cooked enough that the birds and pigs will munch it right down.
I don't own a microwave, we tossed ours out, years ago. I found the quality of our meals improved without it.
Pigs and chickens both like cukes, too, but you don't have to cook those!
