My girls are 28 and 29 weeks. Our BR laid her first egg last week and has been laying since then. No one else is laying. Our PR is the same age as her and she hasn't laid. The other 3 (Americauna, GLW, and BJG) nothing. Any idea when the rest of our girls will lay? We are in Southern CA so our weather is pretty mild. Maybe they need extra lighting? I dunno. Thanx!
