It's brown and it looks like chunks of Sand, we give it to them everyday and grain everyday. and they freerange all day and eat buggies to their hearts content.
Where are you located? There are no bugs in forage where I live on New Years day.
If you are talking about chicks and chick starter crumbles, then yes, they need them every day if you want them to be properly fed.
They don't need grain at all because if you read the ingredient label, grain is already in the feed. Adding more to the diet will lower the nutrition.
To deprive them of the nutrients they are known to need in the correct ratios would not be good animal husbandry.
Forget what it looks like. Just read the guaranteed analysis tag and you'll learn that it isn't sand.
The key caveat to all this is that the feed should be fresh. Feed 4 months old or more will have lost much of its vitamin content and amino acids will be diminished. If not stabilized, vitamin content begins to be lost from the day it is milled. Always check the mill date.
I'm returning a bag of Fertrell Poultry Nutri Balancer tomorrow. I brought it home a week ago and called Fertrell with the lot number. It turns out it is two years old. The grain elevator I bought it from is 60 miles from my house. So, I'm going to spend 3 hours to return something the feed store shouldn't have sold in the first place. All the other places that carry it are farther away and they may not rotate their stock either. I'll call ahead for the lot number or mill date any time I have to drive that far.
In the mean time, I'm still looking to enhance vitamin content of my feed. I do have fish meal which I have been adding in moderation.
