We've been very careful and our roos are actually super healthy and not overweight at all! I know people who have cornish cross chickens who are 5 years old or more. The new hens, sadly, are very overweight. So, sadly, the problem may sort itself out eventually, if the pullets pass early. We will take care of them no matter how long they live. But, yes, we're aware that some cornish cross dont live long. But some do.Have a plan B in mind. It is possible that the cockerels may die prior to starting to mate - just the nature of the beast. They are prone to leg problems and heart attacks. If they start breeding they may injure the pullets as @Molpet has suggested. They are large and very clumsy and can cause serious injury to the pullets.
