I took advantage of Meyers 80 cent Cornish X special, and here they are at 6 weeks 4 days. I havent weighed them, but they are like picking up little bowling balls. They are just the most entertaining birds. They are to the point now where they lay down more than they run around,but when I throw out handfuls of scratch they come thundering. They like to get up on things and sit, but when they jump off they just splat. I may open Freezer Camp next weekend for the biggest ones. Id like to get them all done by the time they are 8 weeks. They have always been able to run around the barn, tho I lock them up at night. They do pick at hay and grass, and like to scratch when I throw corn at them. Funny birds. I was pretty happy with these. There was one DOA, but since then they've all been just fine.
