It is very loud. I almost need headphones to stand it when they are all in the same building like that!LOL great video. Thats how it sounds here often at my house. Group eggs songs are hilarious and Im sure a little annoying for neighbors lol. I have 2 roosters that join in when the hens lay and egg.
I also learned the hard way that the group song could mean danger. When I hear the group egg song now I always go running fast to check on them. I wasn't aware that that group song also means they are scared until very early one morning I heard this group song and just ignored it for about 45mins. I finally went out to see what the all the commotion was for and it turns out something had murdered 4 of my young roosters.
