I know it is the time of year for us to begin wondering if they will ever lay. I have some very nice heritage RIR that are now 28 weeks and none laying and really not seeing bright red combs. I see all these RIR starting to lay at 16-18 weeks. Do the heritage lines just in general take longer to start, or is it just this set of birds? I have about 20 of them I am thinking they should haved started by now. Anyone else have the Heritage lines that take some time to start?
