Bird house for a pigeon (Batley WF17)

Can anyone help me I’m looking for a bird house for a pigeon that’s adopted me. It’s a racing pigeon that didn’t go home. I have been in touch with the owner its number was on a ring on its leg. He doesn’t seem interested in having it back so now he’s here with me he disappeared at night I thought he’d somewhere to stay. I’ve just been outside and he’s on top of my sky dish. I’m at Batley so if anyone local can help me I’m sure the pigeon would be really grateful and me too. Thank you xx
