We've incorporated two platforms in the coop interior in addition to roosts. Outside the pop door we also have a 'snow platform' so that in winter the birds can exit the coop even if drifts invade the run. I'd love to see what you do in the snow (and mud) to keep the girls in the light, and clean. Other ideas? It's our first year with chickens and I'm loving it! More pics in the home page link below.
