Our Grey Huey is 21 and was not a flyer. We got him on Dec 1st of 2017 and by end of January he was flying, not real graceful but flying...lots of crash landings. I started him out by just giving him a toss onto our bed over and over. Once he got the idea, he started trying to fly on his own and we had some scary moments as he had some very hard landings. I spent about a month flying out of my chair to go provide a landing arm for him when he would launch himself because he was not real good about hitting his landing rope/etc. and would then crash hard. Eventually he's gotten very good at hitting landings and rarely crashes anymore. He's even flown down our hallway and turned and came back which is pretty amazing for such a large bird. He'll never be super acrobatic like our Greycie that learned as a baby but he's a flyer now.
