So I am building my run. I wanted to set 6 pressure treated 4x4s in to the ground for the wire mesh to attach to. Will the pt kill or make the birds sick??

Great advice. I did this to protect from termites which will still eat at the newer types of "treated" wood.Before setting the post coat them with asphalt or roofing tar for added years to the post.
It depends on what it is treated with. Newer treatments are less hazardous. The wood should either be stamped with the chemical or the supplier should be able to tell you what it is. You certainly don't want wood treated with inorganic arsenic.
Look for products certified as an Environmentally Preferable Product (EPP).
