4 brown (1S,3L)
4 green, 31 brown past week (17S,14L)
1 green, 11 brown past 3 days (6S,5L).

Since I've been tracking size of brown eggs this is the distribution of 3 day production:
(6S,5L) Sa
(8S,5L) F
(8S,7L) Th
(8S,7L) W
(8S,6L) Tu
(8S,4L) M
(8S,4L) Su
(7S,4L) Sa
(5S,4L) F
(5S,4L) Th
(4S,5L) W

Small eggs daily 3 day production totals {4,5,5,7,8,8,8,8,8,8,6}
Large eggs daily 3 day production totals {5,4,4,4,4,4,6,7,7,5,5}

ascending order:
Small eggs {4,5,5,6,7,8,8,8,8,8,8}
Large eggs {4,4,4,4,4,5,5,5,6,7,7}

Small egg production has been increasing over the 11 days for which I have 3 day running totals. Large egg production is noisier, although it does appear to be trending up. Maximum production figures over 3 days suggests that all 4 birds in both cohorts are laying.
