My hens have a very soft, moist, slimy, and light green stool! They start laying in the spring and fall but anytime during the summer or winter (no matter the weather) they wont lay eggs! They are all over a year old and they have a rooster. There is a sheet put up so they can hide from the dogs and they free range AFTER they eat their calcium feed...please help me! My parents are talking about getting rid of them.... :'(
