What is most accurate for weekly weighing during the growing period? Off feed or
At 2-22wks, Cobb BW STD will be dry BW (without feed).
If you have flocks with prolonged feeding time in early weeks, so birds are still on daily feeding, I suggest to weigh bird before feeding time.If doing every day feeding during 2-22wks, weigh birds before feeding is the most accurate way for the weekly sample.
At 23 weeks, BW will back to wet BW again. I recommend to weigh birds 6-7 hour after feed time from 23 weeks.
