Forgive my ignorance, I'm new to this, I've read the FAQ several times but I'm still unsure of a few things. How often does a hen lay? And did I read somewhere that they typically only lay for a few years? But live for 10-14 yrs? What do people do with their hens that quit laying? I'm sure some people keep them around regardless but I assume others don't? So do they rehome them? Butcher them?
