Our girls are only 17 wks old. Their combs and waddles are starting to color up and get bigger. I was wondering whether most chickens laid their eggs in the early a.m. or when? My neighbors chickens are super loud at night, like 9 p.m. and later. I think it's a little odd, but maybe not?? They even get eggs laid after dark??? Our flock is out in their yard by 8 and in the coop by 8. Their choice not mine, but it works. Is this a good sign?
