Hi, my husband and I are fairly new at keeping chickens... we have our first "set" of hens who have aged out and are not laying anymore. We have separated them out from the younger girls and moved them to their "retirement home." The plan is to butcher them, instead of having pets. My question is, should we switch their feed to a finisher feed, or can we continue feeding them layer pellets. I don't intend on keeping them for very long, I just want to make sure they're good and meaty. Thoughts? Experiences? Thank you!
