Wild flowers or grass?

The garden is getting some renovations as well as the house. Phil and his dad made the chicken enclosure smaller to allow for a shed ( Do not worry they still have lots if room to run about). whilst Hilary and I dug over the vegetable patch which has turned into more of a weed garden. I do quite like some of the pretty flowers that came up including forget me nots and buttercups. We don't really have the time to keep the vegetables so do I grass it all over or maybe make it a wild flower section?
