Found our first egg out of our 3 GLW hens. They're about 22 weeks old. We just switched them to Layena from the Medicated Start and Grow on Friday, just 4 days ago. Set up a light timer, as the coop was very dark and felt like they weren't getting enough light to begin laying eggs. So, how long should we wait before actually eating the eggs, since they were just switched to the layer ration? Is 4 days enough, or should we wait longer? Thanks!
