Fast food chain Whataburger is scaling back on breakfast.  

Because of a national egg shortage, the San Antonio-based fast food chain says it will now only be serving breakfast from 5 a.m. to 9 a.m. on weekdays. The brand previously served breakfast until 11 a.m.

The national egg shortage is a result of bird flu, which NBC News reports has sickened more than 44 million chickens.

Whataburger stressed that the egg shortage is a supply issue and that consumers’ food is safe. 

It’s unclear whether other fast food chains will be forced to follow suit. 

News of Whataburger’s limited breakfast is a major disappointment to fans.
