when chickens are young you can use food or treats to gather them, they catch on fast.
I can go out and yell Chick chick and have a fowl stampede heading at me because they know I have food or treats.
If I need to put them up I'll call them then drop food as I go in the pen, they me follow right in.
In the evening they will go back to the pen to roost before dark, I just go out and shut the door right at dark.
I live out in the sticks and have to have a
predator proof pen, coyotes, fox, raccoon, possum stray dogs and even hawks have got them before.
These pictures are the new pen as it was being built, the wire on the ground around whole building was later covered so nothing can dig under the pen. Don't have pictures of the finished pen but one end " 8x10 " area was insulated with windows and 6 nest boxes accessible from the outside.
Backyard chickens website is a good place to learn about raising and keeping chickens
