Quick question- I got two barred rock hens the other day.
One was laying, one wasn't. The one laying layed every day, and then stopped suddenly. I have the hens in with my pullets, and I was feeding them starter crumbles so I figured it would be OK to let the hens eat those too, as long as I gave them veggies and egg shells for calcium. Could that be a reason she stopped laying?
They will stop laying when they move. Just give her a couple of weeks :-)
