update on keets free fly time

Thank you for the advise, my keets are back in their cage, two of them did on their own and the other two alittle help from me, they seem to be okay and more calm now, I have had one of them for a year and the other 3 for 8mos. I can handle sky the older female, blue the younger female is starting to be more trusting, sunny and blue the males wouldn,t let me touch them in the cage, but outside of their cage was different, seemed to be happy and more trusting, I could handle them with no biting, all of them actually. I have put a large plastic tree in there for them since they have been back in the cage, should I leave their door open for them to come and go as they please, I have a sign on the door for noone to enter while keets in flight as we have a 14 room house that we are redoing, alot of escape routes, so for now they have one room, when we have company it will be safer for them to stay in their cage, but we will see how this goes for now, any more advise will be gladly welcomed, I just want my little feathered friends happy and stay healthy, never have had a problem with them, don,t want to now, thanks
