Birbs, netting might be the way to go. May also want to look into making some DIY wicking beds. Works good for the dry and wet times. Your squash looks chlorotic from here, give it some nitrogen, plant beans next to it in the long run. Three sisters guild (Corn, beans, squash). Aloha.
You gonna try round 2 on corn? Not sure if you watch Bill Merell the green garden guy over by Mountainview he's pretty knowledgeable on growing stuff and was successful with corn he got from U. Of Hawaii, his latest video has some corn in it he's growing now
Zucchini fruit can turn yellow for a number of reasons, including: Lack of pollination Zucchini plants have separate male and female flowers, and if the female flower is not pollinated by bees or other pollinators, the fruit will start to grow but then turn yellow and eventually die. This can happen more often in rainy weather when pollinators are less active. To improve pollination, you can try attracting pollinators or hand-pollinating the flowers. Soil conditions Both overly dry and waterlogged soils can cause zucchini to turn yellow and wilt. Heavy soils that don't drain well can become deprived of oxygen, which can lead to yellowing foliage, browning of leaves and stems, and wilting. Planting zucchini in raised beds can help you control the soil. Nutrient deficiencies Deficiencies in nitrogen, potassium, or magnesium can cause distinct yellowing patterns. Pests and diseases Pests like squash bugs and diseases like powdery mildew can also cause yellow leaves. Calcium deficiency Inconsistent watering can lead to a calcium deficiency, which can cause blossom end rot, a condition where zucchinis start to grow and then turn yellow and die. Some varieties of zucchini are naturally yellow
