Hi there, I have two hybrids in an eglu and moved house about 4 months ago. Since then they give quite a constant rate of distressed calls / squawks, even when the're out their run. At first I thought they just wanted out the run for a bit, but they keep on going. The main change in the move was that they are now on pebbles rather than dirt and there's a lot less weeds for them to munch on. Could the lack of foliage and dirt to scratch on explain the noise?
