Thanks Ghettostar, Im still in the planning stage haven't actually built the coop yet, im going for the rabbit hutch style coop because i have a small garden and i do have a brick 8ft by 7ft shed but its damp inside and full of rubbish plus i dont want to be inside a loft with the pigeons with the risk of pigeon lung, so by doing the rabbit hutch style it would me being in the open when attending the pigeons. Not sure on overall size of the coop yet only want one big enough for a pair to enjoy them.
