Not saying they won't lay this early, I have seen sex link hens lay as early as 4 and 1/2 months, and I think my dad had some California Whites that laid at about 4 to 4 1/2 months. So if yours are leghorns then they jsut might start early. My two pullets are still small I would not want them to start laying for a while yet, they really need to grow first.Well if someone had leghorns they might have eggs!
