Hi Emma

Welcome to the forum.

Pekin hens are lovely. We had two and they lived to six years old before moving to the great chicken house in the sky.

There are a few priorities with keeping hens. That they have shelter and a safe place to roost. They also need a nesting box. If they are in an enclosed run spread a layer of gravel over the run every so often so that they are not tramping about in mud. Always feed them well - layers pellets with corn for treats. Change their water every day and clean out the chicken house once a week dusting the perch and bedding with mite powder. We used to use hay in the nesting box but found that this led to breathing disorders. We now use woodchips - the sort that it used for hamsters etc. We buy a big bale in bulk.

Hope that this helps
