New chicken mommy here and planning for our 8 chicks arriving in April. I am considering fermented food for our chicks. How do I know how much to make at a time? And if I make it, how long does a batch keep if they don’t finish it all? If I’m using chick starter crumbles, do I strain off the mash before giving it to them or just scoop it out and serve as is? Thank you in advance for your sage chicken wisdom!
