I don't see why the sight of eggs in the nest wouldn't push a hen on the verge of broody the rest of the way to full broody.
I had an older GLW go partially broody out of season when the chicks I was raising in the run were six weeks old. I had never heard of such a thing, but there was no doubt Su-su was broody. She had the unmistakable "broody cluck", and she was fiercely protective of the three chicks she adopted, raising them, teaching them, feeding them until they were four months old.
Somehow, being in proximity to those chicks triggered her hormones. She may have been broody earlier, but I was too preoccupied with the chicks to notice. It wasn't until the chicks were mingling with the adults that I noticed Su-su hovering over them.
