Hen cackling a lot

[The Ricker]

Just recently one of my hens starting all this cackling... It appears she wants to lay an egg but cannot. Is there something I can do and should I leave her alone? She is eating and drinking. She will stop cackling for a while and follow around with the other hens in the yard. Please advise.

She is probably just doing the laying song. If she were egg-bound she would be straining a lot and be ruffled up.

I hope this helps.
