New hens introduced to flock

[Jbank19]

I have 4 Rhode island reds 1 being a rooster and all 4 months old. I was given 4 other hens of different breeds all about a year old. Question is the 4 hens I was given wont go into the coop at all except for 1 that just goes in to lay and right back out. They even sleep on the perch in the run at night when my RiR rooster and hens go in to sleep. Is it because the rooster hasn't accepted them yet or ? It's been 5 days now. Any tips? Also 3 of the 4 new hens I was given stopped laying. Is it because of the change of their environment possibly? I've had chickens for a few years now but never introduced strange birds to a flock before.

Stressful events can disrupt laying.

I would carry them into the coop after dark and place them together in a spot away from the established birds. They will likely figure it out for themselves after a few days.

you might want to watch and see if one of the original hens is being a bully, sometimes you can pull that bird out for a few days and it helps everyone settle in.
