I have 5 hens and 1 rooster that are the offspring of free-range "mutts". We have had them in a chicken coop with attached run since they were day-olds. We don't have much room in our backyard and we have our garden in the sun so the coop is under a tree. They are 6 1/2 months now and haven't laid any eggs yet. Their combs aren't very red yet either. Our son has 3 hens from the same brood in his backyard and his have been laying for 1 month now. Could it possibly be that they are in a shady area (it does get some morning sun)? We feed them good quality layer pullets and they have plenty of room and nesting boxes. Any ideas? P.S. Yes, they ARE hens. Thanks!
