What a beautiful coop you have! Glad to hear you are enjoying your flock. When you're ready to add more birds, read up on isolation and integration...they both play a vital role in things going smooth.
Hi Stacey and welcome from Central, PA! feel free to come on over and join us on the Pennsylvania-unite forum. We always have plenty to talk about and even have a "chicken train" that occasionally travels across the state, picking up and delivering birds and eggs from each other
