We have ultrasound. It's the first year I've used it, though, so I'm still learning. It seems that as they start to really pound the food, the follicle growth rate increases. This seems to be in the 15-25mm range. Still haven't had an ovy, but we should be close. The one closest has 26mm follicles. She only has 4, and she's a smaller girl (1100 grams), so I don't know what to guess as far as what size they'll be when she ovulates. Time will tell.
becareful once they hit around 26mm they will usually have follicle growth that is very fast. I was checking them every 2 weeks and one of my females went from 4/1 @ 27mm to 5/1 now 40+mm and my other females when they hit the mid 20's had just about the same results. what I run my temps at compare to your temps could have a slight effect on the timing. keep a close eye on them and good luck
