I have an egg eating epidemic... I filled an egg with siracha sauce. They loved it. At least it seemed like they did anyway. They are eating eggs from under my broody hens, and I'm losing a lot.
I am glad that you brought this up. My hens will gladly and eagerly eat the hottest peppers on the planet. Just because you or we like, or detest something is no guarantee that our chickens will share our human likes or dislikes. To put it another way, if your hens sleep on a tree limb, is that an indication that you will sleep well perched on a limb 30 feet off the ground?
