NO. APPEARING: 20-80 males (plus others; see below)
The leader of a kobalt clan has 21-24 hit points and a retinue of guards (3-12) with 15-20 hit points each, protecting both him and the planar-traveling kobalts (PTKs). Another 4-16 guards with the same hit point range as above will be assigned as lair guards, crewing positions near the entrances. These guards are in addition to the other kobalts encountered.
Females will be found in a kobalt colony, equaling 50 % of the male population. Young kobalts are equal in number to about 10% of the adult males. 2-20 heavily protected eggs will also be found in the colony. Except for a few remarkable females who work through the hierarchy to become guards or are hatched with the Planar Travel mutation, most females and young are noncombative unless the colony is attacked.
Standard Kobold Organization: Gang (4–9), band (10–100 plus 100% noncombatants plus 1 3rd-level sergeant per 20 adults and 1 leader of 4th–6th level), warband (10–24 plus 2–4 dire weasels), tribe (40–400 plus 1 3rd-level sergeant per 20 adults, 1 or 2 lieutenants of 4th or 5th level, 1 leader of 6th–8th level, and 5–8 dire weasels)
So maybe...
Organization: Gang (4–9), clan (20–80 plus 60% noncombatants plus plus 1 kobalt with mass planar travel mutation per 20 adults and 1 3rd-level guard per 20 adults and 1 leader of 4th–6th level), or colony (40–200 plus 1 kobalt with mass planar travel mutation per 20 adults and 1 3rd-level guard per 20 adults, 1 or 2 lieutenants of 4th or 5th level, and 1 leader of 6th–8th level)
