Hello and welcome to BYC!
Glad you joined.
Your birds are way, WAY past large enough to be moved outside to a proper coop with a heck of a lot more space than they currently have. They need to be able to dig holes in the earth and dust bathe daily, sunbathe weather permitting, scratch around and run and flap and preen and be happy healthy chickens.
