just keep the coop dark and not east facing
summer is tougher than winter. cocks will crow through the night on clear nights, when the birds get up, when/if something disturbs them in the night but some seem to start at 2am and crow on the half hour until daybreak regardless. they then shut up just as its time to get up
I really like the Scots Greys. They are hardy, feisty and ok layers. They are not stupidly flighty like my rumpless are and my hybrids were! I hope you decide to get some-the breed society is quite active atm and there's two Facebook groups as well
