I've never tried yellow squash. I've allowed my torts access to zucchini and pumpkin vines in mid summer to autumn, given that it grows quickly and doesn't slow down during the hottest months, but honestly, I've never grown yellow squash. Instinct would lead me to think it's alright, but hopefully, someone who has experience with this will be able to tell you.
I feed it to mine regularly, quite a lot of it. It's a nutritious food source that all of mine enjoy. Try grating it into a salad of they won't accept strips.
