lmao...you could always stick a few fingers on her back side...my layers have four finger spaces between their pelvic bones...their vents are also large and moist...my non-layers don't have that much space between...maybe it would tell you if she is super close or just kinda close?
starlover, looks like yours may have a little longer to beginning to lay....her comb doesn't look quite as red as a bird who is laying just yet...sorry someone on her said alfalfa also helps...couldn't hurt to try
The rest of my girls are doing really great...I have some more speckled sussex coming shortly...and a couple of JG for good measure...I have GOT to get rid of some birds! Im glad your Snow White was okay! Im always terrified when one of mine doesn't show up now Never had a hawk attack before her.
