I agree, I would go ahead and cycle her, but continue to feed her as much as she will eat. All my girls who "want" to breed eat GREAT up until close to ovulation. I tried a 1200 gram girl last year, she went through all the motions and bred like a champ, but never did develope any follciles. I think this was her way of saying "no I'm too small"
But it certainly did no harm in trying.
