@Tsundererra: a lot of toys that they make for parakeets use twine, because it's fiberous and thick. So they have a harder time getting stuck on it. Though don't ever leave any metal clips from a toy in the cage, because one of my boys, managed to lodge it through the underside of his beak, cracking it. Luckily he lived but his beak on the bottom is cracked. He had dried blood on his chest when I finally found him hanging there. I had to feed the metal part through the soft part under his chin because he did a great job getting himself hooked. He was shaken up for a couple days but he's completely fine now.

@Tsundererra:

Yeah, he was up there and I know he liked playing with it, so when I looked up at him, I thought he was just playing, but then I noticed he was trying to pull off. He had been hanging there a while because the blood that was on him was brown and caked on his chest.(Mind that I had just gotten into the room for the night, since I usually spend the day in the living room) I got him down, washed what blood off I could, and put him in this tiny cage I had when I bought my original first two back in 2009 from a farmers market. It's like a little transport cage that's good for separating someone for recovery. He was there for two days, started eating again and so I put him back. He's his same fiesty self now, but I try not to get any toys with those hooks anymore. It's those kind they usually use for keychains. The ones you have to press in the long part to open, and it's usually hard to do. So he was both dumb and smart enough to get it open to get his beak stuck in it.
