I have 13 layers and 2 are not laying. They are 6 months old and the rest have been laying frequently. I got them from Murray McMurray in Ohio.I found out which ones were not laying by the "Putting fingers in between the bones" trick. They both got 1 1/4 - 1 1/2 and I have small hands and another one of my chickens got 4.They are a maran (I don't know what type) and another one that I do not know what type it is. Please HELP!
