It happened to me when I was involved in a project for someone’s PhD in animal behavior/training, or something like that (it was decades ago).
We devised a little ‘play’ for the chickens to perform, and they all trained perfectly - that rooster learned to walk a tightrope, pull a tiny wagon, etc.
But when I tried to get it used to its little costume, it became enraged.
I decided then that I’d only ever keep chickens for eggs - roosters aren’t the best eating, anyway :-)
They are not the best eating, what was the costume.
