How the planner uses this breed
The flock planner does not rank ISA Brown from a single overall score stored in the database. Instead, it weights individual traits differently for each household. Cold hardiness matters more in harsh winters; heat tolerance matters more in hot climates; docility receives additional weight when children will handle the birds; and housing size can prevent a breed mix from being recommended even when its preference score is strong.
