Well the mare is always huge and always looks pregnant. Last year I was so convinced that somehow she found a stallion and was pregnant. We didn't breed her (tried but she never cycled well enough for us to order semen) anyways she got HUGE, milked heavy and actually waxed up and did acted like she was in false labour. It was at this exact same time. I assumed it was the same thing. I looked at her, thought "Oh you are doing THAT again?! You really are a mess. Stupid mare."
