So my hens were laying only about 16-23 eggs per day. Even though there are 40 of them. But then a series of events happened and now I'm down to 2-4 per day. This is driving me nuts! All in the same week I got a new puppy, who I bring with me into the coop because I want to train him to be friendly with the birds. That same week I got two new roosters and did away with the old guy. Also that same week the weather turned bitterly cold. That was about 3 weeks ago though and now they are all used to the new roosters and only 2 or 3 hens still freak out from the dog. The rest come right up to him and don't seem bothered by him at all anymore. I have a good lighting schedule in there, a timer and a bulb in each coop. They also didn't lay well all summer long for some reason. I should be getting more than 20 eggs from 40 chickens. Thanks in advance for any input.
