its best to let the birds come out on their own as opposed to trying to get them to come out ...once fully trained at least with perch training as you will at some point need to retrieve them with a perch...to return them to the cage
on their first outtings expect a few crash and burns as they fly into something and then fall ..do not rush to them at this time just let them be as rushing to them will only further frighten them...they do survive the first couple of bangs and falls then get to learn how to navigate thru the house and land more safely...remember this will be their first times using their wings and LEARNING to actually fly...
be sure there is nothing for danger and you birdie proof the area from cieling fans being on to standing water anywhere...toilet seats down and doors locked so someone dont try to go out or come in when they are out and then you have a escapee...also if any other pets in house they need to be closed off in another room...cover any LARGE mirrors as they dont know its a mirror and will try to fly into them...just pull drapes at first over windows or slider doors...eventually this wont need to get done but that wont be for months as they will need to figure all this stuff out...
training is more difficult with two especially if they are in the same cage and with females its always a bit more tedious to train them...
you will get it in time and so will they...just remember always do not force and be patient and slow in your movements around them...
