BeckyPA, the swing looks like a cool idea... I'm thinking of just letting the little cluckers roam free in the yard, but will see how often they run off to the neighbours. Predator wise we're a bit luckier here, hawks and foxes are probably the biggest concern.
Yeah, the coop is maybe a bit more complicated that we originally planned, but I thought its better to just build it as big as possible in the beginning, otherwise my better half would probably have me building another one in a few months when she goes even more crazy with the chicken-obsession.
Next time we hatch some more I think 3 weeks will be the absolute maximum I'm willing to keep them inside, we just finished cleaning in here and the dust was everywhere. And don't worry if one turns out to be a rooster, it will make a very efficient wake up system =P
