I have watched you struggle with the heat and the bugs and adding mulch to your garden. You should consider starting a permaculture food forest that is sustainable with the biosphere and your chickens as you will see in the videos and will provide food forever rather then yearly cropping with all that hard work. A 7 layer food forest can be constructed with just human edible plants if you like and will bring birds and the right insects to your land. These youtube clips should give you a general idea.
