One of the main agriculture trades in the UK is Hen Laying. Most homes in the UK will have a basket of eggs in their kitchen as we speak. The English Breakfast consists of a fried egg or even scrambled egg.
The UK has a good reputation for animal welfare, and there are several codes of practice. Hen Laying or Chicken farming is no excuse, with the RSPCA patrolling what chicken farmers can and can’t do. One stipulation is that every chicken farm must have some sort of back up power or standby power in case there is a power cut. In the north of England where there have been many power cuts, more and more farmers are purchasing UK Built Diesel Generators (with CPS providing many of them).
