Two of our light Brahmas (1 year old) have made it their job to announce all happenings in the nesting area. Entering, laying, nesting, and leaving all require the egg song on hormones. Usually they take turns announcing, but the "fun" really begins when they decide to have an announce off. The egg song in stereo, as loud as they can.
Our roo, Magoo, started crowing at age 8 weeks. He crows for just about any reason, bored, alone, being male, finding food, wanting food, wanting attention, or just because. Right now he is our only roo that crows. It is not only a sound that makes us smile and laugh, but because crowing requires his whole body we enjoy watching him also.
After reading the above comments about Sussex hens I'm worried about our 6 Sussex pullets. Right now they are very quiet, rarely making more than a peep, at 13 wks old it is only a few weeks before they are laying and we may be in for constant noise. Where are the ear plugs?
Our coop and run are about 50 yards from the house so even when our windows are open we really enjoy the sounds of our chickens. It helps that we don't have any near neighbors to complain.
