This is true. Or, if you have chickens and decide for whatever reason they’re not working out in your flock, it’s OK to eat them. My goals for my flock are always changing. If I try a breed and decide that it’s not what I want, into the freezer they go.If you want layers for many eggs it is wise to buy breeds that are known for good laying like Leghorns, Barnevelders, or laying hybrids for the industry if you don’t care about the looks or a long life.
You can check what breeds lay many eggs and are known to be unfit as a broody before you buy them.
FWIW, I’ve had several hatchery BOs, hoping for them to go broody. One bird, one time. I don’t think the hatchery birds get the memo as to how they’re “supposed to” behave.
