In short: rooster pose starts in lotus. The arms slide down through the gaps between the thighs and calves, the palms press into the floor, and the whole folded body lifts off the ground on straight arms. It depends on a deep, comfortable lotus, so it is an advanced pose and never a place to force the knees.
Rooster is one of the few arm balances described in a classical hatha text, and it remains part of the Ashtanga primary series and the Iyengar repertoire.
The name and the old text
Kukkuṭa means rooster or cock. Kukkuṭāsana is one of the fifteen postures of the 15th-century Hatha Yoga Pradipika. In Pancham Sinh’s 1914 translation, the yogi takes lotus, carries the hands under the thighs, and raises himself above the ground with the palms on the floor. The same text builds on it: from rooster, grasping the neck with the hands and lying back gives Uttāna Kūrmāsana, the upturned tortoise. The Iyengar Yoga (UK) syllabus lists Kukkuṭāsana at plate 115 of Light on Yoga, directly before Garbha Piṇḍāsana. AshtangaYoga.info describes the Ashtanga version as an arm balance in which the arms support the body downward through a lotus seat.
Making the pose work
Everything depends on how high and tight the lotus is. The higher the feet sit in the hip creases, the larger the gaps behind the knees and the further the arms can slide through. Thread one arm at a time, as far as the elbow if possible; a little moisture on the skin helps it slide, as AshtangaYoga.info notes for the related embryo in the womb pose. Then press the palms down, straighten the arms and lift, drawing the knees up toward the chest.
In the Ashtanga primary series, rooster follows embryo in the womb directly: after nine rolls on the back in the lotus-and-arms shape, the practitioner rolls up with some momentum, releases the hands from the face and presses them into the floor with straight arms. The pose is held for five breaths. AshtangaYoga.info mentions that some practitioners add an abdominal churning exercise (nauli) here, with the alternative of simply breathing calmly; that is a traditional add-on, not a requirement.
Precautions in plain words
Rooster combines full lotus with arms pressed between thighs and calves, which increases the twist at the knee if the lotus is not truly open. Never force lotus for this pose; knee pain is a stop sign. Avoid it with knee, ankle or hip injuries, and with wrist or elbow problems. Pregnancy is not the time to start it. Learn it with a teacher.

Upward Rooster (Urdhva Kukkutasana)
Upward rooster turns the idea around. Instead of threading the arms through the lotus, the folded lotus legs rest on the backs of the upper arms, high near the armpits, and the body balances on the hands with the arms straight. The Iyengar Yoga (UK) syllabus lists Ūrdhva Kukkuṭāsana at plates 417 to 419 of Light on Yoga, and in Ashtanga it belongs to the third series as versions A and B. AshtangaYoga.info’s description of version A starts in a tripod headstand: the legs fold into lotus in the air, lower until the shins reach the armpits, and then the arms straighten and the head lifts for five breaths. This is a very advanced pose that needs a steady tripod headstand, an easy lotus and direct teacher supervision.
Preparation and what comes next
Prepare with lotus held comfortably for several minutes, scale pose (the same lift without the arms threaded), and hip openers such as bound angle and fire log pose. In Ashtanga, rooster follows embryo in the womb and is followed by bound angle. After the pose, release the legs slowly and stretch them out in staff pose.
You will meet rooster in Ashtanga (primary series), Iyengar and traditional hatha practice.
