I take your point, but .......
Well.... Unfortunately it is not quite that simple. As I understand it, it ain't just a guideline, it is actually illegal to feed "kitchen scraps" to poultry, even if they are not being kept commercially. Kitchen waste includes anything - even if it is of purely vegetable origin - if it came out of a kitchen, whether it was a commercial or a domestic kitchen. From the perspective of the home chicken owner, who maybe has a very few, basically "pet" birds for interest (and a few eggs) this is clearly bonkers. What can be the possible problem in cutting off the outside leaves of a cabbage, and then feeding it to the chickens???
From the perspective of DEFRA it is a measure which helps to reduce the spread of animal diseases. I believe that the real target of the legislation is the feeding of animal by-products to livestock (not just poultry, but pigs, bovines etc). This is sensible. It reduces the chances of another foot-and-mouth outbreak. Or, maybe, "mad cow" disease. Yep, the legislation is overkill for the home chicken keeper - and for us it seems illogical. But I understand why it's there - and how would you simplify it?
Far easier for DEFRA to have a "catch -all" than a raft of complicated rules which differed depending upon how many chickens you kept, precisely what you fed them on. who you were then allowed to pass the eggs (or meat) on to - even if you didn't sell it. So it's a lot easier for them.
If you want to be "squeaky clean", then there's a solution for us also. Not such an easy one for some, though. Nothing can be kitchen waste if it does not enter your kitchen. Therefore, if you segregate vegetable waste outside of your kitchen, or cut off unwanted bits there, then it's perfectly legal to feed it to your poultry. If you do it inside your kitchen, then no.
At this point you may be asking yourselves 2 things:
1. If the point of the legislation is to stop the feeding of animal by-products, and I'm being very careful to avoid doing this, then is what I'm doing actually ethically wrong as opposed to technically illegal?
2. Who is going to follow this up and prosecute me anyway?
However, in answering these questions, always bear in mind - it is illegal!!
Oh, and of course I take no responsibility for the precise accuracy of this information - or for any prosecutions that may follow!!!
