It doesn't look overcrowded to me, but you can turn the pot over and let the rootball slide out to see if there are roots encircling the bottom of the rootball, which usually means it is potbound or rootbound.
Bird's next ferns are epiphytes, meaning in the wild they grow attached to tree trunks or other vertical structures. So, they wouldn't require a lot of soil, but rather fast draining soil.
