How long does it take for a hen to lay after worms?

[demonic]

I have a hen named tiny and she recently had an egg internally broken(?) in her and worms. After caring for her she became healthy and happy and loves to fly and run around. She acts completely normal but it’s been a few weeks to a month since and she still hasn’t laid an egg. She’s still a little light so I’m curious if eggs are even forming. Was the worm medication I bought a rip off? I ordered the safeguard dewormer for goats and used it on her, is this a good worm medication for chickens? She acts fine so I assume it worked I just wonder how long it will take for her to lay eggs so I know she is 100% fine. My other 2 hens are laying.

by the way she’s only 11 Months old, not to mention that I see her sitting on the eggs and after like a minute she gets up. She does his throughout the day but she’s been Doing it for like 2 weeks
