This is our first time and we are only trying 2 meat birds to slaughter. I think the birds are cornish X's but the feed store only new them as being meat birds. I just want to know what is the ideal size to butcher before the meat gets too tough. My husband use to be a chef and I want this to be good for roasting. Both of them stagger when they walk as if they are gonna tip over. However, they still chase after bugs in the pen with the other 2 layers the same age. I think its close to the time but I want to get the most out of them as there are only 2. They are almost 8 weeks. Can anyone help? Any answers would be appreciated.
