For the most part, my girls were pretty quiet. Some clucking now and then and the occasional false predator alarm sqwuak, but otherwise what I expected. However, in the past few months (they're around 2 years old now) they've been going crazy in the mornings. From 7-12, they'll give short, sporadic concerts. Their vocalization seem to be mostly egg songs (cluck cluck cluck PAKAAAH), but I thought they only sang those before and/or after they lay an egg. However from 7-12, they sing the egg song intermittently at least 4 times, and they don't even lay an egg. They don't even go in the nesting box. There are also the shrill clucks/screams when a predator is around, but 95% of the time when my girls scream there is no predator around. Also, most of these alarmed screams come from just one or two of my girls and not the whole flock, and when I go out to see them, they usually stop when they see me. It's getting to the point where I'm very scared that the neighbors will get my girls kicked out of the neighborhood. I'm also planning on building a run (they free range now). Will their sudden shortage of space increase the noise? Please advise!
