Can anyone tell me when (what time of day) do chickens lay their eggs? My 6 girls are only 4 to 5 months old and haven't started laying yet, but if they lay in the morning, I don't want to let them out of the coop to early before they have all laid their eggs. Also, we only have two nest boxes in our coop and there are the 6 hens. Is this a problem? I've read where people have build multiple boxes and they all use the same one.
