I responded to an ad to take in 4 buff o. hens that will be a year old in March. I have 3 hens in a shed already.I am wondering what could I put together to hold the hens until I can add them to the 3 in the shed.I was thinking of using a large dog crate/cage I have,and setting that up in the garage.Would that be a decent place for the girls till I can add them to my mini flock? What have you used? Also,when the time comes to add them do I take the hens into the shed at night and put them on a perch,or should I just put them in the shed during the day while my other girls are out in the yard/run? This is my first year with hens and first time taking in new hens. Do I have to wait 30 days to add them to my flock? Is 2 weeks enough to see if they have any diseases?
