Cockatrice (Summoner Variant)

Bite. Melee Weapon Attack: +3 to hit, reach 5 ft., one creature. Hit: 3 (1d4 + 1) piercing damage, and the target must succeed on a DC 11 Constitution saving throw against being magically petrified. On a failed save, the creature begins to turn to stone and is restrained. It must repeat the saving throw at the end of its next turn. On a success, the effect ends. On a failure, the creature is petrified for 24 hours.

Summon Cockatrices (1/Day). The cockatrice has a 25 percent chance of summoning 1d4  other cockatrices. A summoned cockatrice appears in an unoccupied space within 60 feet of its summoner, acts as an ally of its summoner, and can’t summon other cockatrices. It remains for 1 minute, until it or its summoner dies, or until its summoner dismisses it as an action.
