Hello, and welcome! Glad that you joined us! I would build a better coop and run for them. There are plenty of good coop building idea's here at this site. You can pick the best one that fit's your need's. Those pre-made coop's are usually pretty flimsy also, and if you live in an area that has strong wind's, they can blow apart. My first coop was like that. My chick's were still in the brooder at that time, so thankfully I didn't loose any of them.
