I have a small table laying flock of a dozen birds. They lay very well. Honestly, an egg a day from everyone, almost without an exception. Two days ago, I noticed we were short a few eggs at collections. Then yesterday, only two eggs! And one of those had a whole in it and had to be tossed. My girls are all less than a year old, and just started laying in February. They have 14 hours of light in their coop, and a fantastic diet of protein, grains, greens, and vitamins - nothing has changed there. The only change has been the addition of a rooster to their pen in the last week. He's a gentle roo, and doesn't seem to be stirring up any trouble. No body seems sick, or stressed. I'm baffled as to what is going on. Could this new rooster be eating a dozen eggs a day without me seeing signs of shells or spillage in the nest boxes? Anybody have any guesses?
