I have 5 laying hens, all about 13 months old. While they'd previously all been pretty quiet (squawking a bit when they laid eggs, but that's about it), for the last few weeks the noise has been almost constant loud, squawking starting at sunrise and lasting most of the day. I thought at first that it might just be one or two of them, but I think it might be all of them taking turns making noise. One of the hens is currently broody so she's pretty quiet, but I wonder if that's somehow agitating the other hens? The broody hen has been sitting in the nesting box that none of them use anyway, so I don't think it's that they want to be where she is. I'm not sure this is relevant, but they started laying at the end of last summer, stopped for about a month during the summer, and then started laying again this spring. Are they destined to be loud chickens forever? Or do hens go through noisy phases? We have our chickens illegally, so I'm nervous about them being a giant pain for our neighbors.
