Two male and two female cockatiel

Three birds are about a year old and one male other is a few years older. Both males sing and the females are very cute as well. I am looking to find a suitable home for them and I would only sell them to a good family who doesn’t want to use them for breeding They are not hand tamed. They are very cute. They like to be able to get in and out of cage. They don’t like to be kept in cage all the time. Please tell me about your experience with birds and where you would keep them, etc I would like the two male and the two females go to separate homes Thank you
