Hiya, Newbie here!!

Hello Kiea.  I'm not surprised you have fallen for your new chickens.  It seems to happen to all of us! 

It is a good idea to keep your new girls confined for a few days to be sure they are settled in before letting them out into the garden.  Anything from a few days to a week should do it.  You will see when they confidently put themselves to bed each night that they are settled.  You shouldn't have to round them up and put them away.

Some chickens are more likely to fly than others.  This depends on breed, and on individual temperament.  I don't know about Warrens so hopefully other people with experience of the breed will be able to help you.

My six chickens of different breeds have never tried to get out of my garden.  They are certainly capable of getting to the top of the fences, but they choose not to leave.  For this reason I have never had to clip their wings, although some people do clip wing-feathers to limit their flying ability.

I think you are very lucky to have hens that enjoy being handled.  In my mind there is no such thing as too much handling.  In fact if you are familiar with the way your chickens look and feel, you are much more likely to spot potential problems (eg weight-loss).  So go ahead and give them all the cuddles they want! 

Welcome Kiea 
I would agree with what Lindeggs and ANHBUC have said.  Enjoy your girls and be prepared to want to increase your flock.  They can really become addictive
We love seeing pictures on this forum so if you can download some of your girls that would be great.
