Ok. And when I get more hens, should I just lock them all up again for a few days? Or can I just do Like normal ( keep them in a cage with food and water around the others) for a few days and then just let them out and hope they stick with the original 4? Mine can, as I have mentioned, get out of the new fence. But when I come to feed them they come right through it to me at their current pen. So I'm hopping if they are attacked some how they will be smart enough to just slide by through the fence to safety within the flock
