First post, I'm not finding any definite answers online, so I figured I best defer to the opinion of those with much more experience:
About 8 months ago, a co-worker of mine was going through some life changes and had to get rid of his chickens. My partner and I raise Bobwhite Quail, and decided getting some chickens wouldn't be a bad idea. So we brought home 2 Araucana sisters, some variety of bantam, a Chocolate Maran, and an unidentified rooster.
Other than the bantam (she has TWELVE, four week old chicks right now), the hens are pretty far past being productive. We get maybe 1-2 eggs per week from each of them. Not really a concern, we primarily took them into our care to save them from the stew pot and watch them free range around the yard (5 acres, but they stay pretty close). The chicks we're planning on keeping as layers once we can positively sex them.
Between grower, layer, and broiler feed, which would you choose as a "maintenance diet" for 5-6 year old chickens that don't produce many eggs anymore? I'm thinking of switching them to an organic whole grain feed, but I'm not sure which blend is best for their well being.
We're feeding the adults a pelleted layer diet right now, along with whatever they can find in the fields/wooded areas around our house (and a Washington summer means A LOT of bugs). I found a company called Scratch and Peck Feeds that seems to offer some decent products, and they're local to us.
I'm leaning towards the grower at the moment, since we'll need it next month when we transition the chicks of starter feed. But ultimately, it's 4 chickens, so a bag of anything is going to last for a while.
By the way - Never having had chickens before, it's REALLY COOL to be able to sit down in the grass and have the hens run over and eat scratch grain out of your hand.
