Feed stores run on chicks. Chick related impulse buys make up a large % of a feed store's total business, and forces customers back each month for feed, and inevitably....more chicks. It would hurt their business to be honest about how much space Chickens need, and any coops that fit the bill would be priced out of reach for impulse buy customers. That applies mostly to big chain stores, I've found small local feed stores that don't sell coops are much more honest about their requirements-they want you to get hooked on chickens and keep them healthy for long term feed sales.
