thanks a lot guys.
vermontcat- yes, i have had them both since they were babies. we got them at the pet store two years ago in december, so they have always been with us. after having the birds for half a year, they were used to us and everything was fine, but then we went on a short vacation and left the birds with my grandmother, who took care of them. when we went to pick them up again, they were shy around us again. do you think this could have affected them? and one time, i was cleaning the cage and sky got scared and flew out. (she doesn't have her wings clipped.) she hit almost every window and door on the main floor and even managed to make it to the top of high furniture. it took about 20 minutes to actually catch her.
popcornbird- i was planning on taming the birds and even thought of teaching them tricks, but my mom refuses to let them out of the cage and doesn't want their wings clipped, so i guess that's out of the picture.
i pet and try to play with rocket daily because he isn't afraid, but sky is, so i don't. should i try to anyway?
thanks for the advice, much appreciated.
