I have 2 BB hens that have not laid. One of them is about 9 mos old, very small, the other is probably about 11 mos old. I didnt raise her. Is this normal for waiting this long? The 11mo, is squating but not laying? She is fed laying pellets, corn, sunflower seeds and free ranges. I am planning on worming in the next few weeks with valbazen. We just finished with the wazine.
