Origin: Formed within English, by compounding. Etymons: hen n.¹, day n.

Etymology: < hen n.¹ + day n.

A day regarded as unit of measurement in estimating the egg productivity of hens. Cf. hen housed adj.Hen days are used to measure productivity by dividing the total number of eggs laid in a given day by the number of hens and expressing the result as a percentage; cf. hen housed adj.

1939 Educ. Method 19 73/1 Thanks to scientific breeding and better care, the modern poultryman is able to average almost twice as many eggs per hen-day as his grandfather did.

2016 Mycotoxin Res. 31 41/2 Laying intensity was expressed as the percentage of number of laid eggs divided by the number of corresponding hen days.

As a modifier, with the sense ‘of, relating to, or measured in terms of hen days’, as hen-day average, hen-day production, etc.
