Can broody hen lay day after hatching chicks?

[LovelyNumber143]

I moved my broody hen and her eggs to a separate brooder on day 17 (Saturday). She had 9 fertilized eggs under her. Two hatched on day 20 (Tuesday) and 5 more today. She was out and about in her brooder and I noticed three eggs in her box. One was definitely not there before. I pulled it and candled it and sure enough it was a fresh egg. Is it possible she laid an egg a day after her first chick hatched?

I’ve had a few of my broody hens lay eggs in the 14-20 day range so normal for me.

Might have been laid by another hen

Much more likely to be another hen.
My broodies usually go back to laying over a month after the chicks hatch.

They stop laying while they are broody, so it's unlikely her.
