Ours are really loud too....this time of year the "egg drama" is a little ridiculous. Several yelling for a couple of HOURS b/c someone else is already in their favorite box, the one in the box yelling at the interlopers ogling her nesting box, ones who are laying elsewhere "singing" (ie YELLING their egg songs) ...repeat 18-20 times per day...I have a blue copper Olive Egger that is as load as any roo. Her egg song is outrageous.
DH had had to grab some of the worst offenders and bring them inside to try and break up the 'singing' ...lol. Last time one of them snuck off an laid an egg in his closet next to his shoes. Now she purposely tries to sneak back into the house to lay....he should have known better...
