Getting confused. Is there basically grower feed, for chickens up until they get to be laying age and then a layer feed? Seems like I'm hearing different names, but is it really only two kinds?
Generally you'll hear starter, grower, finisher (there are layer and broiler formulas of developer/finisher) and layer. Starter and/or grower can actually be fed from the day a bird hatches to the day it dies at a ripe old age. Starter tends to be slightly higher in protein (20-24%) than grower and is in particles that are smaller. Grower is generally a little lower in protein 18-20%) than starter and the particles are slightly larger. Layer feed is even lower in protein (16-18%) and is enriched with calcium (4% as opposed to the >1% of the other formulas) to support a hen's body being able to shell and expel eggs. Then there is the different forms feed comes in - crumbles, pellets and "mash". The pellets are more associated with layer ration as the feed intended for the younger/smaller birds is presented in crumble form - "mash" is also a layer feed.
