I was given ten 3-week old chicks back in June by a friend who wanted to get me into chickens. She had EEs from the same batch, same hatchdate, same hatchery that she shared with me. I have 3 EEs who started laying at 21 weeks to the the day and a couple of her 10 just started at 25 weeks and 4 days. We keep in contact a lot and we've determined that we give them the same food from the same vendor except that I mix crushed meal worms in my feed daily and often treat them with whole mealworms out of my gloved hand. The grower mash has 18% protein and layer has 16%. After being frustrated she tried what I was doing by adding crushed mealworms to their feed and wouldn't you know, she got eggs in two days. What we have deducted is that the protein is the key factor to get the girls started laying. Is this commonly known or did we stumble onto something?
