So this is my first chicken raising journey in 20 years or so. I have 24 Rocks in a 25 square foot brooder and the weather is just not cooperating in wisc. to get them outside into their new tractor coop. They are extremely confinement liking as I had the lid open halfway for fresher air etc. They jump upon top and walk around and then drop back down inside! Have read a few stories of chicks going nuts when they are taken out of the brooder. Hope mine like the tractor and green grass! The tractor is my own design and needs painting yet so that is still in the shop too. The dust they kick up is incredible! My shop will need a super cleaning. So what is a good age for butchering rocks for grill and roaster?
