Is this a ovulation? We ultrasounded her 1 month ago, and her follicles were about 30mm. We ultrasounded her today a her follicles were so big, they didn’t fit well on the scree. We estimated they were about 40-45mm. She is brighter than normal, usually being greyish. Also her lower body seems stiff. These seem like signs of ovulation, but I want to make sure! Any help is appreciated Thanks!
Its a bit hard to tell since she’s chunky… When was the last time she ate?
Does she show any signs of tail suck? It’ll look like all of the fat and meat is sucked out of her tail, and in extreme cases her belly might concave a bit.
Taking a guess from this though it is possible that she might be at 40-45mm
