Now that it is breeding season (I have bantams and Anconas) I feed layer. I prefer 18 percent protein layer feed.In general I do have a problem with changing to a 16% layer feed when the birds are 16 weeks or a bit older, before they reach adult sizes. Not a good choice if actual maturity and longevity matters. Commercial 'egg factories' don't care, their birds are all gone before two years of age anyway.

Except to the chicks I have just hatched which get chick feed.
My youngest are 5 months old. Obviously its not ideal for the Delawares which I am raising for meat, but it is more inexpensive. Until two weeks ago, I fed all flock or chick feed but considering my number of birds, it is simpler to buy only two varieties of feed now that the and not three.
