They are all the same age, born on the same day. I believe only one is laying currently as I only get 1 egg per day. Again they're just a few days shy of 20 wks. I can't be sure I've never raised chickens before.
I say I took a crash course in chicken care. And still learning! This is a great resource for information on all things chicken!
And a great place to get help in emergencies! Currently have a hatch going on and the 1st one hatched had the yoke sac still attached. Still watching the lil one.
