I think you have to look at what happens if you have losses, and what you're willing to lose in exchange for the price of raising them. How much is your time worth taking care of them if you happen to lose 1/2 your flock when they're 4 weeks old? Maybe you can afford that loss, in exchange for not having shelter for them? or maybe minimal shelther? or protection? I think it depends on how much money they cost you, too. It seems no matter where I get them from, it costs (with shipping and all) about $2.00/chick. I've done about 30 in each of my two batches so far - and this time I think I can get the total cost of (organic) feed for them to about $200. total. I'm only doing a small number, so the shelter for just a few was worth it for me when I annualized it out over the 10 years I except that coop to last. for instance, it cost $450 to have someone make the coop for me, but if I run 3 batches a year then the coop is costing me about $15.00 / batch. For me, for those 8 - 10 weeks that I'm feeding the chickens, that $15.00 is worth it for me not to lose my investment. just imo!
