We have to process our Cornish X one week earlier than expected. So yesterday at 5 weeks old some weighed 5#'s, the processor said to take off 1/3 of the weight to get a good estimate of how much it will weigh dressed out. I'm new at this, I think I'm using the right terminology. Anyway, if I want my birds to get heavier, do I need to feed them 24/7 the last week or what. We will be processing at 7 weeks. How much will they gain in 2 weeks if we just feed them the 12 on 12 off schedule? I couldn't find the thread for weight on here. Thanks for your input!
