So I have a young GC about 3 months now, and I've had him for about 5 days. He has progressed great so far! He super confident in his cage, eats all day, plays with his toys, preens and just today has decided to use his voice. I've had him get used to me by having him follow my hand thats on the outside of my cage while holding his favorite treat, an apple. He has become pretty good at that and seems pretty confident having my hand near him while he eats his apple. He goes about his day while Im around and definitely has let down his guard. So today I decided that I would open the door to his cage to see if he wanted to come out. I have a perch installed on the outside of the cage for him to hang out on. After about 10 minutes he comes out, but almost immediately makes a break for the glass door to the outside. Since he is clipped (I picked him out after he had been clipped so couldn't ask to keep him flighted) he glided a bit to the floor and then ran the rest of the way to the door. Obviously he doesn't know there's glass there. So for about 10 minutes I tried to get him to come to me with an apple to avoid having to chase him around and grab him to put him back in the cage. But after a while I started to get nervous it was stressing him out to much because he kept trying to fly out. So I had to pick him up (us lightly as possible) to get him back into his cage. After I got him back in, I put the apple in caged and he snacked on it quit rapidly. He is super active and I feel bad having him in the cage all day, but how do progress to having him out without him trying to make a run for it every time?
