My 5 LF girls are a year old, and laying consistently, but the eggs are small. Only one hen produces an egg close to 2 ounces. Most of them are around 1.5 ounces. They get laying pellets, meal worms, frozen Japanese beetles, a few table scraps, small amount of mixed bird seed daily. Water all the time. There is calcium free choice. They free-range about 3 hours daily. Their breeds are EE, White Rock and Production Red. What else can I do?
