I have been raising naked necks and red rangers for meat this year. I have my first few batches of CX and I haven't raised them before. But it has been swealtering hot here. Mid 90's and dewpoint in 70's. My CX are 4 weeks old and it seems they are barely over a lb in weight and not eating much. Drinking like crazy though. At this rate I am guessing they will not be ready for End of August. Does the heat hamper their growth rate that much?
