I am about to move my three-month-olds to their new coop. They've been raised in the basement thus far, therefore they are used to an environment with little temperature-change and no wind. I've read that chicks raised indoors should be slowly exposed to the outside, like "hardening off" indoor-grown seedlings in gardening (an hour the first day, a few hours the next, then a half day, then a whole day but still in for the night, then out). But I am wondering whether this is really necessary in summer when the outdoor temps are pretty consistent and warm. My plan is to put the birds in their coop and keep them in there for a few days before letting them out into the yard. The coop has screened vents and windows, so it will allow some sun and air without "full exposure." What are peoples' experiences with moving indoor-raised chicks outside? Do you do it all at once or with some form of gradual exposure? Could I endanger my birds by moving them into the coop all at once? Any advice or experiences would be much appreciated.
