It certainly is an interesting idea. I would for sure keep the cat separate but within sight of the chickens at first, just to make sure he's not going to attack them, and also that they're not going to attack him. I've got two cats, one of them is scared of the chickens, and the other wants to have them for lunch. She's smaller than the hens, but she went after one of them once. All she got was a mouthful of tail feathers, because the rooster chased her off. I would not trust a cat in my chicken coop, at all, especially if you're going to have young-ish birds in there as well.
