Hey guys so my aviary is finally built and my birds have all moved in this weekend. My birds are settling in very well and are having to get used to having people around them a lot more than when they lived next to the woods on my friends land where they were very secluded. Unfortunately where I live now is in a housing estate and very echoey! I never noticed before how loud and how long the night time flock call lasts. I have 6 adults cockatiels and 2 fledglings and they start their flock call around 7pm and it goes on for at least two hours. Is this normal or is it because the surroundings are new? We are concerned the neighbours may complain so I am going to sell one of my pairs and I always sell the babies. But if they are still this loud for that long every night I will be forced to rehome them all. If anyone has any helpful tips on how to make the call not last as long or to fill the sound abit it would be very gratefully received!
