Baking in camel dung 🐫

A talented Haredi girl from 💯 Shearim Al-Shaqa'a studied at the Open University, enlisted in the Intelligence Corps and continued as a researcher and lecturer at the Hebrew University
She settled in a certain Bedouin tribe, lived with the mukhtar, researched him, and came to the Agassi forum to lecture on her research, and they uploaded it to YouTube in their own way.
She observes the mitzvot. And in general, she doesn't eat meat 🍖 for reasons of vegetarianism, as well as maintaining a unique touch and many other things that are quite similar in their tradition to observing the mitzvot, so it went quite easily for her.
It turns out that some of her family came to her in Sinai for Shavuot (on a mountain that might be Mount Sinai?) They brought cheeses from the land and baked cheesecakes for the holiday. It turns out that they bake in ovens that are hollow spaces dug in the feces of 🐫 camels and donkeys.
Is it kosher?
