Brits have been warned of a possible shortage of eggs with some stores starting to ration how many shoppers can buy.
Supermarket shoppers at places like Tesco, Sainsbury's and Lidl have already noticed signs in stores, warning of supply issues.
In one Lidl branch, a ration of three egg boxes per customers has been put in place, according to a picture posted online.
It isn't clear how many stores are implementing this same measure.
Meanwhile, pub chain Wetherspoon has warned customers that the "temporary supply issues" may mean its breakfast menu is altered in some boozers.
It comes as the price of a box of a dozen eggs has already risen by more than 22%, according to official figures.

Last year, the UK produced 11.3 billion eggs and had to import another 1.4 billion to meet demand.
Here is what you need to know.
Why are egg supplies under threat?
Farmers are being hit by a mixture of rising prices and an outbreak of bird flu.
The British Free Range Egg Producers Association (BFREPA) told the BBC farmers were being squeezed by the price of chicken feed - which has spiked due to the Ukraine war - and sky-high energy costs.
Its members claim they've only received between 5p and 10p more despite the price of a dozen eggs rising by about 45p in the supermarkets since March.
"Feeding hens is now at least 50% more expensive than it was, and energy prices have soared in the same way that consumers have seen their domestic bills rise," the BFREPA said in a statement.
"Spending on fuel has grown by 30%, while labour and packaging also costs more."
A recent survey of 163 farmers affiliated with the BFREPA show 33% have already reduced or stopped their egg production.
Farmers are also suffering following the biggest ever outbreak of Avian Influenza, which has resulted in millions of birds being culled or killed.
There has also been a knock-on effect of birds dying during the heatwave this summer.
However, the Department Environment, Food and Rural Affairs (DEFRA) has denied there are any supply chain issues.
A spokesperson said: "We understand the difficulties the bird flu outbreak is causing for farmers, however the laying hen population is approximately 38million so it's unlikely to affect the overall supply."
Which shops are being hit by supply chain issues?
Shoppers have been sharing photos from in stores, showing bare shelves where eggs should be.
One Tesco customers posted an image on Twitter showing signs that read: "Due to the hot summer we are currently experiencing low availability across our egg range.
"Sorry for any inconvenience."
Another photo posted from inside a Sainsbury’s showed a sign that read: "We are currently experiencing supply issues across our fresh egg range.
"We are working hard to resolve these and apologise for any inconvenience caused."
Similarly, an Aldi shopper tweeted: "Have you stopped selling fresh eggs online because of bird flu? I could not add any to my click and collect order.
"I will have to buy them from somewhere else now separately."
Another said: "I shan't be shopping at your Great Barr store any more. A lot of the shelves were bear [sic]. No eggs again."
And one Lidl customer asked: "Why have you no eggs in your stores?"
Another Lidl shop has started rationing eggs, according to a picture posted by Grocery Insight CEO Steve Dresser.
A sign read: "Eggs are limited to three units per customer to ensure that everyone has the essentials they need."
Andrew Opie, Director of Food and Sustainability at the British Retail Consortium, which represents the UK supermarkets, said stores are "working hard" to " minimise impact on customers".
He said: "While avian flu has disrupted the supply of some egg ranges, retailers are experts at managing supply chains."
The Mirror has approached Tesco, Aldi, Sainsbury's and Lidl for additional comment.
Meanwhile, Wetherspoon has made a huge change to its breakfast menu across some pubs in response to the supply chain issues.
Punters will notice that there are other options available to replace the eggs, such as hash browns, sausage or onion rings.
Wetherspoon spokesman Eddie Gershon told The Sun : “We can confirm that there are temporary issues with egg supplies at some Wetherspoon pubs, 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.“
