I don’t know if it is possible without an operation and that would shorten their lifespan by years and is ridiculously painful and cruel to the chickenOh Boy..I live in the city & not allowed to have a roo. And hu;by says 3 birds max. Anyway to increase her estrogen levels so she'll lay again? I've heard seaweed (kelp) powder. I started feeding her that today. Anything else I can try?Thank you!
