I have just inherited a naday conure named Perky. He seems to be just that - a perky fellow. I would like to know what I may and may not give him to play with. For example, the people I got him from said he loves wood - he's chewed his swing to bits, so I wondered if I could give him a pine cone to chew at and perhaps extract the cornels? May he eat unshelled almonds? I gave him one and he demolished it pretty quickly, and seemed to enjoy the challenge, but I'm concerned about whether such things have hidden dangers.
