Hi,we have some Dark Cornish from Meyer hatchery, they are 20 weeks. Some grew fast and are pretty big now. A couple are on the smaller side, I notice the one's that are smaller are the better foragers and seem to do ok with free range, I am trying to decide what to do with them, allow to grow to maturity and then harvest, keep one for breeding with out BO roosters and for minimal eggs. Have not been able to find alot of information on them. Here are some pictures they aren't the best. We have 4-5 and one i cannot even get a pic of because she runs and is skittering. 3 are pretty friendly and two are not.
