A shortage of one key ingredient has forced the closure of almost all the 900 KFC restaurants throughout Britain and Ireland – there’s no chicken available.

Feathers are flying over the issue, especially over concerns that some KFC workers aren’t getting paid.

The Associated Press reported that the closures occurred on Monday, as the company apologized to customers and blamed the problem on its new delivery partner, DHL.

KFC first apologized for the problems on Saturday. In an update Monday, it listed almost 300 stores as open, but did not say when the rest might join them.

It said those branches that remained open were operating a limited menu or shortened hours.

“We know that this might have inconvenienced some of you over the last few days, and disappointed you when you wanted your fried chicken fix — we’re really sorry about that,” the company said in a statement.

DHL, which recently took over the KFC contract from Bidvest Logistics, said that “due to operational issues a number of deliveries in recent days have been incomplete or delayed.”
