Society doesn’t work on edge cases. But for the sake of argument:
If that’s all the animal products you eat, these chickens are not selected through the common practice of grinding male chicks, the hens are going to die of old age, etc etc etc - for what I’m concerned you’re vegan.
Veganism is about ethics, not diet. Diet is a mere consequence. Lab grown meat is more vegan than coconut gathered by enslaved monkeys (yes it’s a thing).
So if you fine one such farm where animals are never killed or otherwise exploited then by all means, eat those eggs and call yourself a vegan. But something tells me you won’t find it.
