If any of you decide to try this... pinching the pubic bone and wiggling it to see how flexible it is... I would just ask you to be extremely careful. It is very very easy to break these little bones in a layer breed. I imagine it's pretty easy in larger, heavier birds as well. You will cause your pullets/hens unnecessary pain and inflammation and may even disrupt her laying. I don't think the bones will heal if she continues to lay and cause them to be moving every other day. So, please folks, don't do this unless absolutely necessary.what he means here is basically pinch the end of the pelvic bone so you can see how thick the bone itself is. Because the bigger, thicker the bone, the more meat and the less eggs you get. so hens with thinner, more flexible bones will lay more eggs than girls with thicker, less flexible pelvic bones. That is what he is doing in Fig 11, pinching one pelvic bone to see the thickness of it.
