Seasonal behavior change?

[Genetics]

My bee, who is 1294 grams, and had never missed a meal a day in her life, hasn't eaten two weeks in a row, and is hanging out on the cool side, and roaming more.

Same thing with one of my ladies, she is 2200grams, has been eating very well until lately.. She's stopped eating, roaming a lot, trying to get out... I have introduced her once to two of my males (at different times of course) and she has locked with both males, but the last week she wont lock with any of the males either.. She gets calm when she is with a male, but no locks ...
