Ventilation is a huge factor in a loft. I don't think you can have too much, as long as it doesn't let in rain.
I went a different route than the entry bobs for my loft. I built this little contraption called a "Sputnik trap" and incorporated it into a little aviary. I hinged that expanded metal "cover" as an anti-predator door, so in the evening when I think they're all back in, I can just flip it up and they're totally secure.
I don't close it every night, but I try. I had (what I think was) an owl hitting my loft every night I left it down. It would get in there and kill 1 or 2 pigeons then leave. After keeping it closed up every night for a month or so, he seems to have found better eating somewhere else.
The 110 conibare traps I had set on top might have scared him off too!
Bank, you're gonna hate those horizontal 1x2's that the pigeons are setting on. It's gonna make it a bitch to clean out. I'd suggest taking them off and making a removable floor for each box. In other words, just cut a piece of plywood, (or whatever you have left) just a little smaller than the box, then screw that 1x2 lip to it individually. That way, you can just slide out the individual boxes and clean them out. Just a suggestion from someone who has some difficult places to clean himself...
