What is holding the wood pickets to the frame?

“He waited seven more days, and once again he sent out the dove from the ark. 11 When the dove came to him toward evening, he saw that there was a freshly plucked olive leaf in its bill! So Noah knew that the waters had receded from the earth”
Nice idea but I think your proportions could be improved. The longest extension should be at least 1/3 the width and not as deep. There are many existing decorative rafter tail designs available.
Use a hat from plastic plate

hi
doves and pigeons feed their babies by giving them something called pigeon milk -- partially digested food material (seeds and liquid) from the parents' crop. it's actually one reason why orphan baby pigeons or doves can be more easily fed by humans, since we have the means to duplicate this kind of food material and feed it to the babies, including that you can feed once or twice a day only. we don't have to constantly go back and forth giving insects or live insects the way that other birds feed their young.
35C? Do you not have AC, dude?
