Hi everyone! I have 3 lovely birds - a Buff Orphington, Ameraucana, and a Dominique. Since last summer or fall, they've been incredibly noisy all the time. They piped down a little bit during the cold, dark months, but are back at it again. They always have food, water, and treats to choose from and this squawking doesn't seem to coincide with egg-laying. It's not a cute little, "Bock bock bock." It's more of a "Waaaaaaaaaaaaaaaaaaaaaaaaaaaaaa" belted at the top of their lungs. Any thoughts about what might be causing this or how to make them be a tad bit less vocal? Thanks!
