It's hard to tell with her. She looks pretty thick throughout right now, but this phase (if ovy was just missed) you often can't tell. In the next few weeks leading up to laying you should start to see more and more swelling. More and more laying in unusual positions to allow the skin to stretch out as the eggs get bigger, instead of a nice coil.
Palpating can be really tough to get the hang of. Even if you aren't having much luck, keep at it each year and you will get better. The key is having her relaxed enough where you are feeling. If she is tensing up it's pretty impossible to feel, so it takes really getting the technique down of holding just the right place that as she glides through your hands, it's not a place that she is using her muscles to move. Much past ovulation you won't be able to feel anything as the egg density changes, so probably not worth trying with her anymore this year. When you finally get it down, it can be incredibly useful to tell where she is pre-ovulation so you really know when stop putting the male in and when to be watching for ovulation.
