I came up with this calculator to formulate feed when corn prices started going up. Some of the ingredients get pricey to try and find. I found that a lot of them can be purchased in bulk from feed mills. The chickens love it when they have fresh ingredients in their feed. I have found it increases egg production. My silkies and polish never go outside so good feed is important for both their diet and their emotional well being. Please download and use this calculator as a copy and do not edit the original. Below is a screenshot with show feed pre-loaded. The link above allows you to download it as an excel spreadsheet.
