Could anyone tell me what it is in layer pellets that make them the standard feed for chickens?
Is it simply because its high protein or is there something else in them that they are in need of?
If its simply protein, there are so many other sources that makes me wonder if I need pellets at all!
I would love to hear opinions from those who are far more experienced than me.
Layer feed isn't the standard feed for chickens in general. It is the standard feed for chickens that are actively laying. Chickens that shouldn't be eating layer feed are young birds that haven't started laying yet, roosters, molters or any bird not producing egg shells.
It isn't high in protein. In fact, it is lower in protein than starter or grower feed.
Starter, grower, finisher, layer, etc.. are intended for a specific age bird in the commercial industry. We, as small holders, must work with those formulas.
In general, the vitamin, mineral and fat content is pretty consistent among all the feeds. Also, in general, starter is the highest in protein (to build small bodies), grower a little lower protein, layer is lower yet and finisher about 15% protein (for the last couple weeks of broilers or a pre lay pullet diet and cockerels.
All the feeds other than layer have about 1% calcium. Layer has about 4% calcium. The only thing other than the additional calcium is that the proportion of calcium/phosphorus/vitamin D needs to be appropriate to build strong shells.
