nothing obvious, but to me she just seemed off. after we determined it wasn't a blockage and found she had an enlarged proventriculus she was started on metacam. the next day i examined her cage really well and found that she had chipped paint off the bars. she seemed normal, but i know every nuance of her personality and behavior so i pushed for the lead and zinc tests and i'm glad i did because she responded immediately to the chelation. it affects birds differently i guess, but with her she wasn't sitting puffed and sleeping, but normally she's being a complete troublemaker/into everything nonstop. she was eating, but because i kept offering her different things all day and night and weighed her 3 times a day and making sure she drank every couple of hours, she had heat 24/7. so she appeared pretty normal to people that didn't know her like i did. her levels were low. i think it was the paint chips (i found them in her poop) that caused a blockage/irritation then she passed it and kept food down, but had low level tox and even low, it was affecting her because she did improve immediately with the chelation and she hadn't really improved after being on metacam and baytril. don't know if any of that helps, but just keep an eye out for subtle signs. may be worth the testing if you think he could have gotten into something. maybe go over the cage and quicklinks and look for marks or signs of chewing?
