In the UK it is illegal to feed kitchen waste to your hens. It is ok, however, to make feed specifically for chickens. Our hens really like a mix of oats and whey… a sort of cold porridge… so last weekend I decided to make this for them.
Whey can easily be separated out from milk using a bacterial culture. Thickening the mix by the addition of rennet makes straining the curds off much easier. And if you allow the curds to drain overnight, you maximise the amount of whey that you can extract.
It’s also possible to remove extra solids from the whey by heating it to just below boiling point, allowing it to cool again and then filtering through muslin once again. I started with 3 litres of whole milk and ended up with about 1.5 litres of whey. Of course I had lots of waste curds, but that was ok because I turned them into soft cheese. In addition, the solids that come out of the whey as a result of heating are otherwise known as ricotta.
You see, it’s not illegal for humans to eat the waste left from making chicken feed…. how convenient!
