After two days of headaches I've given up on aspen. I don't know if I got a bad bag or what but it had a pretty strong smell. So I went out and bought the boys some fleece. I really hope the fleece works because they were popcorning like crazy and seemed really happy in it. I also got some good first pics of them so I'll post them soon. Thanks to everyone who has suggested the fleece at one time or another.
