I have 30 cornish X and they are 4 weeks old. They seem to have stalled out this week on growing but not eating. I have been weighing them about every other day and this week they are stuck at 2- 2 1/2 pounds. I am adding more food and more waterers because I can't keep up. Does anyone supplement with other food? I am feeding feed store high protein food. Considering they are half way to their final age, shouldn't they be bigger? Is it normal to have a period of not gaining? I was doing 12 on and 12 off but feel that I need to go to giving them access all the time. I want to see these guys get big and fat and soon. Any ideas?
