No luck again.. I put the big green one in his cage yesterday, it looks like he got half the green stuff off and then gave up. He had dropped it, so I put it back in his cup, then he dropped it again so I put it back in the cup, and he dropped it again! So I left it at the bottom of the cage to see if he would go down to get it if he got bored, but no it is still there. He never goes to the bottom of the cage though. I will try again in a day or two with all three. I agree, I think they do need to ripen. The christmas and queen nuts were ripe already so I put those in the freezer. I left a few of the green ones out and also froze the rest.
