I have was told (and have read) that the chicks need to be closed up in the coop for a few days when you move them outside. What I don't know is this: Should I move them to the coop during the day or at night? Will they know how to roost right away if I put them on the roosting bars? I also have been told that they can go out anywhere from 3 weeks to 6 weeks, but then a book that I'm using as a resource said that for most parts of the country they should go out at 8 weeks. I'm in the San Francisco Bay Area and it's in the upper 40s at night, upper 60s in the daytime. Right now my chicks are 5 weeks old. When is it safe to put them out? Thanks for your advice.
