I have this volunteer come up beside my Call Duck run. Google says it's summer squash and I did give the ducks some yellow squash and zucchini last summer from our garden. It's been growing really well but it's not putting off any fruit. It's growing out and has reached probably 5 ft. It's putting off nice flowers. I know it's getting plenty of water being beside ducks but I just realized that I haven't used any fertilizer other than duck poop that's naturally flowed over to it. My Calls have been reaching through to bite off pieces of the leaves and they seem to LOVE them. So my question is, should I try anything else to get this plant to put off some fruit or just accept that it's not going to do anything except provide some green leafy treats for my ducks? The leaves are safe for the ducks, right? What about the flowers? The location isn't ideal as it seems like a good hiding spot for snakes plus it's running out so far in the grass. Thank you for your time and any input you can provide 
Side note: I just remembered that it did put off one teeny tiny squash that shriveled up and died within 2 days.
