I have 1 white leghorn and 5 NHR that are almost 17 weeks. . I have 1 white leghorn that is almost 16 weeks. My youngest WL, Ms Pissy, has been laying for almost 2 weeks. One of my NHR is laying almost every day for almost 2 weeks. Should my other NHR be laying by now if they are of the same age as the one? How about my other WL? same questions. Now I assume heat can affect the laying process, but if it doesn't affect the 2 that are laying, would it affect one from starting? I am just impatient....tapping foot here for more eggs LOL We are having a heat wave of unusual temps, for a very long period of time !!! Thanks !!!
