I currently feed the Nutrina Nature Wise Chick Starter feed. It's 40 pounds. About how long will that last? I keep feed in front of them at all times. I have four chicks currently. Also, are there better feed brands, treats, or others foods that would be good for them? I'm able to get Kabash brand. I got them March 3rd from Big R. I see mealworms, oyster shells, and feather Crumbles sold at the store but I'm not certain when to feed them that or not?
