My Cornish X (1st group) are just 2days shy of 9wks old. One of the pullets died at 7wks and I had to dispose of her, I was irritated with the time and money (and meal) that I lost. I've been paranoid since then and I check on them several times a day to make sure they're all ok. I processed 2 of them at 8 wks and the live weights were almost 8 and 9lbs. The smaller dressed out at 5.4lb and I didn't weigh the other one. Today I we've had a sudden increase in outside temps and it's in the mid 90's. Some of the larger birds are having difficulty breathing and one of them was starting to become cyanotic. I decided to butcher him so I didn't lose the whole thing. I was planning on doing a couple every night and finishing on the weekend, I never prepared for "emergency" processing. Is it normal for these guys to go that quickly? BTW, the one I did today was 10lb live weight and dressed out at 8.4lb. He would have been 9wks this Saturday.
