i just wanted to warn everyone that hay can be dangerous to birds. I used to have hay in my button's cages but one day while I was trying to exam one of their toes (somehow one of their toenails got ripped off) I saw one of my females tryng to swallow a long sturdy piece of hay (it was about half as long as her entire body). I grabbed her and was able to pull it out, but just barely. I'm so glad I was there at the time because that would not have been good. So since then I haven't had hay or shavings in the cage. I'm too afraid they'll try to eat shavings too. the shavings have little pieces of wood in them and they might mistake that as food. Has anyone else had any trouble with shavings or hay? Maybe that's sometimes the cause of a bird to die, but you wouldn't ever know unless you had an autopsy done.
