Calculations and values for hatches, purchases, sales, deaths due to illness, deaths due to other causes (predation and theft), and consumption.

Parameter description	Chickens	N (number of households or communities considered)	Mean value	SD value
Household ownership, o	Xo,i—number of chickens owned in household, i	–	–	–
Death due to illness, d	Xd,i—number of chickens dead due to illness in household, i	3,326	0.437	0.752
Death due to predation and theft, n	Xn,i—number of chickens dead due to predation and theft in household, i	3,326	0.0565	0.243
Hatch, h	Xh,i—number of chickens hatched in household, i	3,303	0.7474	2.962
Purchase, p	Xp,i—number of chickens purchased in household, i	3,326	0.0176	0.126
Sales, s	Xs,i—number of chickens sold in household, i	295	0.0270	0.0781
Community ownership, o	Xo,i—number of chickens owned in community, i	–	–	–
Consumption, c	Xc,i—number of chickens consumed in community, i	2	0.498	0.007

For all k in o, d, n, h, p, s, c.

(1) The household (o, d, n, h, p, s) or community (c) level proportions are calculated as $H_{k,i}=\frac{X_{k,i}}{X_{o,i}}$.

(2) The mean value is calculated from the proportions as ${\mu }_k=\frac{{\displaystyle \sum _{i=1}^N{H}_{k,i}}}{N}$.

(3) The standard deviation value is calculated from the proportions and mean as ${\mu }_k=\frac{{\displaystyle \sum _{i=1}^N{H}_{k,i}-{\mu }_k}}{N-1}$.

Calculations for hatches, purchases, sales, deaths due to illness, and deaths due to other causes (predation and theft) are calculated at the household level, while consumption is calculated at the community level.
