Wood! I posted an ad on CL to see if anyone felt like donating me any wood. Someone did, and I went to get it tonight. To my surprise it consisted of new sheets of plywood, several new 2x4s, and different sized other pieces for nest box building or perches. I now have nearly all materials needed to make the loft, will be 8 feet if I can get away with it in the backyard. Then I'll work on the smaller aviary's loft later, they're completely covered in colder weather already. Now if only I could run in to another local adopter like I do every few years who wanted some, that would leave even more room for new ones. Since there are about a billion out there at the moment, it seems like.
