Ok we have had some issues lately with new and older chickens in our flock and have gotten a handle on them. Well they are starting to lay again and I left some 3 day old eggs in a nest as we had been using antibiotic and I ran out of golfballs so just left those in there. Well thought I heard something and went out there and low and behold a BROWN LEGHORN hen is sitting on the nest and growled at me when I walked over. Ok I thought they were non-setters so went and looked again and sure enough breed standard says non setters....these are pure bred birds from murray mc murray about 12-18 months old. What do you think?
