With EEs in can vary by months. If they're not getting extra light, they may wait until spring. 1 of mine started at 21 weeks and the rest followed within the next month. For eggs they needed 12 to 14 hours of light and a minimum of 16% protein feed. I use 20% protein feed to offset tablescraps, vegetation and cracked corn. Some people feed cat food to up the protein. Good luck! I hope you get your blue eggs, mine were all green. So I got some Ameraucanas. Now I have a few blue eggs.
