fawn
麛 centers on a young deer: a fawn. The meaning is specific to a juvenile deer.
麛 combines 鹿 (deer) with 弭, which likely contributes the sound and helps specify a young deer. The exact historical development is uncertain.
The deer enclosure 鹿 wraps around 弭, like a young fawn sheltered by its parent. Picture a fawn hiding inside the deer shape.
For ベイ, imagine a fawn taking a small bay step: bay -> ベイ, and the young deer moves gently.
