Haven't seen or read anything on this YET, but when can I let the chicks go out in the RUN? We are new at raising chickens, so any suggestions? We've had the chicks for one week and they were between 1 and 2 weeks old when we bought them. We have a fenced in area right from the coop.They are getting bigger and feathers are starting to fill in on the chicks. Also, should we cover the top of the run?
