I wouldn't worry about your male getting injured. If he's big enough to be paired, he's big enough to look after himself
Also, if the female isn't keen, she'll usually just avoid the male.
She's just under the 2,000g mark at last weigh in which was about 5 weeks ago. Bigger than she was at this time last year, too so has comfortably regained what she lost from laying the last clutch.
Looks like I've already managed one lock with her and there could be another right now as I type this, but I can't see clearly to be certain. They're under under tree bark and I can't see their tail ends! But she's left her scenting marks in her enclosure and they're both together, so fingers crossed!
I'll leave them together until Thursday / Friday and then separate them to offer a feed two days after. She's keenly eating weekly right now, so will keep offering until she rejects two consecutive feeds then revert to fortnightly offerings and so on.
