These type of record keeping threads tend to peter out as it's a lot of work. There are ways to make the task easy. For example, weight out 10 lbs of feed at a time and keep a tally for weekly total. Same as you did, add up the 10's and weight last one for what was used. Weekly total is enough info. It's constantly changing on a daily basis as they grow until age 10 weeks or so where it will even out. Daily total may be nice at pre slaughter age around 14 weeks old. Also weights of birds is a lot of work if done often. As long as you know the feed intake the bird weight means little until 6 or 8 weeks. The largest birds at that age will be your fastest maturing and good selection base for future breeding. Tag those birds. Weekly or biweekly weight there after is good but enough would be weights week or two prior to intended slaughter and day of slaughter. Then butchered weight. Your graph will be an exponential curve, these are very predictable and easily and accurately interpolated with less data.
