Not all mares wax. Not all mares you can get milk out of. But if you CAN, it will usually get sticky when she's close. Did that answer your question?
Somewhere in here (do a search) I posted a thread with a link of things to look for and how to test the milk.
That would explain why she didn't last year. Could she this year, or does each mare have a different pattern--some wax every time, and the rest never wax? I found that article very informative, thanks for posting it!
My understanding is this, the pre-milk is called colostrum (sp) which is very rich in nutrients for baby's first drink. They wax up for lubrication. She is a real pretty mare and the stud is gorgeous! You are going to have a real pretty baby coming soon! Good luck and thanks for keeping us in the loop : ) can't wait to see the littler gaffer lol!
Okay, seriously? Someone felt the need to report the photos of Lulu? I can't tell much from those pics on my own; I need people to help me and Photobucket apparently thinks it's not appropiate *headdesk*
I think "waxing" is just when leaked milk dries on the ends of the teets. One of my books describes it like the crusty stuff that forms in the corners of your eyes. It's just there! The actual production of milk is controlled by hormones.
