When would it be safe for her to lay again?

If y'all have seen my other posts, my EE had her vent half ripped off. A Dr. friend stitched her up and she's healing very well. I have her in the guest room with a heat lamp, the blinds closed and the lights off to keep her from laying till she's healed. She was injured on Saturday the 15th, stitched on Monday the 17th & today's the 22nd. The dissolveable stitches should be gone Monday the 24th. When do you think it would be safe to turn the lights back on? I don't want to put her back in the coop till she's laid her first egg because I'm worried that the repair isn't as good as it looks and she might have trouble passing the egg.

To complicate matters, I'm leaving town the 31st & if she gets in trouble laying, hubby won't be able to help.

Thanx!
