We have 45 cornish x's on order and due at the end of June. I have been reading this forum for a while and trying to get as much information as I can but I still have questions. When the arrive I am also getting a few easter eggers. I want to keep them together at the beginning in a stall in a shed we are making predator proof. Does about 3 weeks sound good? Then I can move the EE's to their own brooder in my layer coop. I normally feed a medicated chick starter to my layer hens. Should I stay away from medicated with the cornish? What is the food timing for them? How many weeks on a chick starter? Do you then move to a grower for meat chickens? I was told to keep the cornish for 10 weeks and then process. Should we change that to closer to 8 weeks? We have been looking at the PVC tractor ideas. From what I have been reading is that people move them to the tractor at about 3 weeks. Being mid July they should be fine with temperatures. My only concern is predators. How would I make a PVC tractor more predator proof? I have 2 big dogs including a pyr who barks all the time. We had a hawk issue mid winter when they were starving but never had any other issues here. But my hens are in a pretty tight coop. I know we have opossum and there is a bobcat in the area along with bear and fisher cats. We will keep the tractor well within the more traveled dog area. But any ways to make the tractor more secure? It seems like it could be light enough something could get underneath. We will use hardware cloth. Thanks!
