Thanks for the info, Morrigan. I think Jessica has had at least two batches from there and was happy with them. I think you're on to something with the temperature being a factor. I did mine in the fall and it was almost always 70s or below during the last three or four weeks. I specifically remember one day it got to about 85 during Week 6, and my usually wild and crazy marathon-running chickens did not want to get up at all. The next day it cooled off and they were back to their crazy selves. I was thinking about doing a batch this summer, but I think I am going to wait until the fall again. The timing is perfect then because it's warm while they are little and need the warmth and then it gets cooler as they turn into little meat furnaces. Processing is much nicer when it's cool outside also! It sounds like you're doing everything right and know what you're doing, so don't beat yourself up. I know it stinks to have to process early though!
