Starling living under shed

Hi

i have a Starling living under my shed, it’s been there for around a month now. It can fly and it’s flies around the garden and onto feeders etc. 

it’s has the crouch down to get under the shed and presumably stays that way the whole time it’s under there.

It has food and water but I just feel like it should be with other starlings and not solitary.

any thoughts?

thanks
