Great post Deb!
Imo, this is a sign to me that she is ready. So if she has a good build/body condition, I would pair her if she was mine regardless of weight but I would continue to feed as long as possible. If she is on the lighter side to begin with, I would only continue to pair if she continues to feed, from my experience the lighter females eat like crazy through the breeding process and can gain a ton of weight by the time they ovulate. I've started pairing females as light as 1100-1200 grams but would only continue to pair if they stay onfood which mine have. In the end, all the females I've bred that started this light laid healthy 5-8 egg clutches and were heavier even after laying than they were at the start of the breeding process.
