We're expecting 5 chicks from a hatchery in 10 days. We're giving 2 to our neighbor after she lost 2 in a coop fire about a month or so ago. We'd really like to add about 5 or 6 more chicks to our flock rather than just 3. Our local feed store has started to stock chicks. Would hatchery chicks and local chicks be fine to put in the same brooder? And what if they end up being a few days or a full week apart in age?
