I had a batch of cornish x chicks. All died but one. This one bird is almost ready to butcher. We have another batch that won’t be ready to butcher for about 3 weeks. Can I combine the two in one tractor? Will they hurt each other like laying hens would?
But if you want to combine them, yes there is a good chance it will work fine. Try putting it in and watch what happens. If things go badly, pull it back out and go to plan b (raise it alone until butchering, or butcher immediately.)
