I have 5 BLs but I didn't get 5 white eggs until they were at least 30 weeks old anlthough some were laying as early as 20. Maybe they were all laying but just not all on the same day. I still don't get 5 white eggs very often. 
Wow 32 wks, 5 out of the 7 girls are laying now We think the Jersey Giant and the buff Polish are the last hold outs.Of the 17 hens I got as chicks in April, my last holdout just gave me an egg this week - that's 32 weeks.
