Do lots of research before you commit to keeping him. An accidental pet often turns out to be a very temporary one when you realise how much they need looking after.
Your place sounds fine. If you keep him, then dont bother with a small coop "for now". Get a coop 2 or 3 times as big as you think you need. Trust me, you'll be glad you did. You'll end up with more via "chicken math" and overcrowding causes big problems. Next thing you know, you'll be building a new double garage sized coop to house them all in, lol.
