I too would do it earlier, as those birds can be quite fragile and with age they decline fast sometimes. Plus, there are always risks, and I once lost a whole flock of 15 of them to cold rain and they were all about 4 lbs each then, and I thought wrongly they could withstand a cool summer rain. Lost all but one that time, then they have other accidents and I lost the only survivor to sudden death syndrome. She walked right past me (yep, had good legs) and stopped, squatted and had a seizure. I was two feet away and there was no saving that bird. She was about 9 or 10 weeks old. Good luck, but a flock in the freezer is always a better thing.
