Bird flu has impacted a Great Yarmouth pub as eggs are currently off the menu.
The Troll Cart on Regent Road is unable to serve eggs with their meals due to the impact of bird flu.
Other pubs - including those not owned by JD Wetherspoon - are also said to be affected.
Wetherspoon spokesman Eddie Gershon said: "We can confirm that there are temporary issues with egg supplies at some Wetherspoon pubs, including The Troll Cart in Great Yarmouth, due to the current impact of Avian flu on egg production.
“We are experiencing issues in receiving all the supplies we require to satisfy demand in every pub.
"At the pubs concerned, customers are being offered alternative items, for example, hash browns, sausage or onion rings.
"We apologise for any inconvenience."
Norfolk has seen more than 40 cases of the virus since the beginning of October, forcing the culls of hundreds of thousands of chickens, turkeys, geese and ducks.
Earlier in November, a call for trained wildlife volunteers and rescue charities to be given special government clearance to remove birds killed by bird flu from Norfolk's waterways was made in Parliament.
