Congratulations on the new addition to your family! (And I heartily cosign on the change of names! Morek sounds like the final boss in a fantasy role-playing game! Hahaha!)
There are tons of threads on the forum that address quarantine, as well as some good suggestions given by OOwl, but I'll give you my take as well.
A quarantine period of at least 90 days is most effective, IMO, as there are some symptoms that can take 2-3 months to pop up. Of course, some can take closer to a few years, but obviously we're being realistic, here.
You should get your little guy vet-checked as soon as possible, with a full blood panel, fecal gram stain, and disease checks for PBFD, psittacosis, polyoma and PDD.
The PDD test isn't 100% accurate and can give false negatives - as it only detects the virus when it's actively shedding - as well as false positives, so a positive would be followed up by an x-ray of the proventriculus.
Polyoma generally affects baby birds, but it has been known to affect adults as well.
There are other diseases you can test for as well, but the tests can be expensive. PBFD would be at the top of my list, as it is highly infectious and, like polyoma, is a nonenveloped virus... which means it is very hardy and can survive in the environment outside of the host body for quite some time.
As far as your visits to Kyleigh in the meantime, you'll only want to go wearing clothes that you weren't wearing when you interacted with Chips. (Including footwear) Until you know otherwise, you want to approach the situation as though Chips is indeed contagious... for Kyleigh's sake.
Once the QT period is over, and Chips has been vet-cleared, you can go about slowly introducing them to one another.
Sorry to be a bit of a downer, but I've lost a bird to PDD. So I know that these precautions are extremely important. Especially when dealing with a baby bird who has not yet developed a fully capable immune system.
