I have had Ginger and my pastel together and observd two lockups; one was earlier in the season, the second one, last night. Now, her weight up until today had hovered around 1800g. I weighed her today and she is at 2007g. Her last meal was before her shed last week, before I placed the male in there again for a few days and observed the lockup.
So for those who weigh their females through the season; how much weight would signify that the breeding "took?" Do they gain much weight, or maybe does it take more energy to form the eggs, which would cause a weight plateau?
