We are doing our research now for Spring chicks. Do we lock the chicks up in the coop at night? Do we let them roam around in and out of a coop and run all the time? My friend told me that we should use a broom to sweep (train) the chicks to go into the coop at night? I know they are dogs...but, how exactly do we get them in the coop...should they go in the coop instinctively on their own when it is dark?
