Welcome ! Are they just hatched ? As they will need some heat also .I live about 40 minutes south of Albany. We will use a big dog crate on the back porch first. This is my first time trying to add to my flock so I think we need a small interim coop before they go in with our 3 Golden Comets and 1 rooster. We will probably build it ourselves and put it into the big fenced in area that my run opens into.
If the dog crate is big enough ..leave them in that ...
You can make it more secure when it is in the run with plywood or hardware cloth on the outside of it . Letting them out in the run works ...when the flock is free ranging .
Then as they get older you can let them free range too . They will remain separate for a while ..when they get close in size merge the flock ..Be there when you do to supervise so the babies dont get beat up too bad .
