Oh yes! I encourage the chicks to hatch safely by playing them chick noises too!When I was raising brooder hatchery chicks indoors without a broody mama, I played them broody + chick youtube sounds and they loved it. But I hadn't thought of trying it to entice a hen into broodiness in the first place!

My hens pay sharp
Attention and show elevated interest when they hear baby chick sounds.
Even better if you can show them a few real chicks.
