My husband brought home a 1940s John Deer Hammer Mill and wants me to make our own chicken feed. Help?!

Wow. You're really lucky to find it. Pictures? You'll also need a way to steam heat the mixture and then extrude it into crumbles or pellets and dry them. An old Califonia pellet mill would be perfect.

.... but you can also give them moist powdered feed like they used to do.

Making your own feed can't possibly be cost effective. But, there's fun and satisfaction in doing it anyway. It's cheap entertainment.
