We bought a second-hand tin shed cheaply for our new coop and have built it up onto a raised wooden floor with a hatch for cleaning. It's all going well so far but we need to sort out some ventilation before we paint it. We've put roosts around two sides - one side is going to have nest boxes, and above the perches and nest boxes we're going to have broody boxes (just a couple) and space for new chicks. I realise that we need heaps and heaps of ventilation, but I'm unsure of how to do it without getting driving rain inside and I'd like any flashing/covering to still look nice. I have an angle grinder and can cut vertical slots in the tin and then cover with wire, but what then? The shed measures about 2m x 2.9m (6.5 x 9.5ft) and we'll have a dozen permanent chickens in there, but we raise babies as well, so over summer it's not unusual to have 20 or so with the younger ones of roosting age there. We live in a fairly warm, dry climate in the Southern Hemisphere - it doesn't go far below zero degrees C overnight in winter and never snows, but it can get into the early 30s celsius in summer, so it's heat I'm most concerned about - although they'll be roaming free during the day. Thoughts? I'd be really grateful if anyone has photos they'd like to share of a converted tin shed!
