That was a really interesting article copper, even for someone who doesn't have a bird like me. I love animal nutrition.
It's really sad, most pet stores will try and sell garbage food for pretty much all your pets :/ on the other hand, the seed I feed my wild birds must be fresh cause it's always sprouting in the feeder after it rains xD
I found that weird that toucans need distilled water cause they can't have iron o.o good to know though since a toucan/aracari is one of my life goals :D
