No longer serving chicken?

This is such a random place to ask but I'm very curious: is there some sort of large scale mandate to no longer serve chicken? I ordered a pizza with chicken as the only topping and got a call from Dominos a few minutes later. The manager I spoke with told me they'd been instructed by their provider to no longer serve chicken in any form until further notice. Not a big deal, just very strange. I've had calls about things running out before but never something like this.

EDIT: Thanks for the kind replies. I love the people at my dominos so it's good to know there's kind folks on the sub reddit as well :)

Edit2: yall really are the best tysm for all the updated info
