Bee I wish I had a brain as resourceful as yours!! I tend to prefer written data in general rather than rely on memory. OR at least MY memory. lol
I'm going to start writing stuff down. I can't even remember how many weeks old the bunch of different breeds of cockerels were I butchered last fall, and I would like to know. We got them in May and butchered around when school started in September 16+or- weeks? The only reason I remembered weights is I vacuum sealed each bird whole and wrote the weight on the package.
I've always recorded dressed weights on the freezer bags as well.
I researched for a year to find my chosen breed, the Malines. I'm still waiting to hear from the buckeye breeder to try to 'fix' the comb issues I have with the roosters' large, single combs. I might ditch this project for another year & keep working with my Malines as they are. They still need some work anyway. The Malines meat can't be beat though! We roast ours as you would a conventional cornish x. They only start to lose tenderness at 7 months of age. I didn't even separate the sexes & they did well on 15% protein grower ration & will happily free range for most of their food in warmer months. Very easy keepers! I will be separating the sexes this year though & watch for any differences in growth.
