That said, are there any first aid basics we should have on hand? Eventually we'll have a sick bird and it would be good to know if there's something we can give them for common illnesses?
A lot of useful first aid stuff is the same as humans or other pets would use - vet wrap, neosporin, vetricyn (which I even use on myself), epsom salts. Anything more specialized I'd get as needed, as expiration dates are something to always keep in mind.
