coming egg shortage in UK cause by supermarkets

Its not an issue between retailer and seller. The issue is that rising egg prices is causing consumers to buy less. Local store used to have $1.99 sale every weekend and now it's $3.49 on sale with a regular retail price that's increased to $4.99 for a dozen eggs. Demand isn't there with prices so high as margins on eggs is a negative value for most supermarkets on a period by period basis, guaranteed. The demands not there for the product and as such farmers need to find a way to offset the issue.
Most other things you could argue, eggs 100% definitely isn't one of them.
I'm also a store manager in retail, go figure.
