How to tell when they are close to laying

[jamieneenah]

I read this:

"How do I know if my pullets are ready to lay? Generally if they are 5-8 months of age, they have red combs and they are singing you should have eggs. You can pick the hen up and feel between the 2 bones of their bottom. If 3 fingers will fit between the bones they should be laying. If only 2 fingers fit between the bones then the hen will usually start to lay with 3-6 weeks."

But I am not sure what bones are your feeling in between? Can anyone give me a more detailed description?
Thanks

I'm not sure about those bones...I haven't tried to feel for that yet. My girls are 18 weeks and I'm expecting eggs any time now, at least from my Leghorns. Their combs and wattles have grown and turned red, and also when I reach out my hand and pet them on the back, they now squat to the ground instead of walking away from me. That's also a sign of laying.

The bones are like pelvic bones and are located under the vent........Pop
