Given that its already built, I'm not sure they have the option at this point to frame properly. Screwing in some metal reinforcing brackets and building better next time (seems there is ALWAYS a next time...) may be all they can do in the here and now w/o complete disassembly.I am feeling like the roof trusses need addressed.
There isn't great or even good support to keep the roof from being ripped off by the wind.
Since the birds aren't in there yet now is the best time to address those.
Just one short video of how to build trusses.
I'm afraid I really don't have a good sense of Irish weather - a couple weeks on the isle of Jersey in summer is as close as I ever got. Would an open air coop design be more optimal in the future?
