Thank you! Would they be okay with my banties if I got 4 king pigeons to be with them or are you saying separately? I will check on craigslist and more.
		
		
	 
You can try it and see, but they would definitely need to be separated  if the pigeons would raise young, or the  pigeons are young (meaning pigeon is adult size, but  still a squab, 
at 30 days old, the squabs are big)
Among chickens the issue (even bantams)  is establishing pecking order.  Seems that pigeons, and chickens don't speak same language 

  so the pecking  could continue to no end.
There is somewhat similar pecking order among pigeons, with the dominant males being the BOSS.  The rest of the flock seem to live in HARMONY, for most lofts. 
Tight living quarters, and overcrowding is possibly the major contributing factor in chicken, and other bird, fighting situations.   
When I housed my chickens together with my pigeons  in the loft this was the situation/setup. 
The pigeon loft is inside my garage.  It is sufficiently  big in square footage. Estimate, about 60 square feet. 
I keep my chickens there overwinter.  I separated loft into 2 sections,  and in pigeon portion, I place my 2 bantams, and a blind EE hen there. (blind due to a dog attack

, still lived for 2 years , until 11 years old)  There was no fighting  there whatsoever.  In the other section I kept  the remainder of my chicken flock, which were Large fowl.   I only have a small flock of pets, so no overcrowding issues encountered.
I currently do not have pigeons,

 so chickens get the whole loft for their winter housing.
I have 6 bantams.  2 OEGH,  3 Seramas, 1 Japanese Bantam, and 2 Large-fowl
 Welsummer, 2 years old,  and  my Senior Citizen RIR, (9 years old

)
I have communicated with a member here on BYC that wanted to use a common run with separate coops, on each end to house a  few chickens with a pair of pigeons.  The run was totally enclosed with netting.  Thread went kind of dormant, so not sure of results. 
Another person used the same  shed to house a pair of pigeons with their chickens.  Made the upper portion  a loft for the pigeons, and  a separate  exit on top into a separate aviary.  That thread also went quiet, so  not sure how all working there currently.
