I've had a bird hop up in my lap, sit down and fall asleep. I've also tucked cold chicks into my coat or sweater...do those things count as cudding? What about little ducklings crawling up my coat and under my hair? I've picked up struggling birds and stroked their ears to calm them. I've carried birds around for no good reason--I have a little rooster, Squirrelly, who LOVES to be picked up and carried around when there are other roosters nearby. I've had a couple special pet birds that I held in affection, as they died or just before they were euthanized, even though I hadn't made a habit of it before. Frankie the hen and Jeremiah Puddleduck (Jemima would not work in his case) come to mind. If any of those count, then yes, I cuddle my birds.
Kiss them? No, I can't say that I've ever kissed any. It's never even occurred to me, and now that the idea has been presented, I find it rather confusing. I buried my nose in a duck's down once, because it smelled like outdoors and sunshine, and yummy flesh, and I dreamed of BBQ, but I can't say that there was anything affectionate in the gesture
No, you cannot transmit a cold sore or chicken pox to chickens, and they cannot transmit ILT or Marek's to you. No, you cannot get coccidiosis from chickens or give it to them. The species of protozoa that usually affect humans are very limited, and not known to infect chickens. The species of parasite that infect chickens are, well, there's quite a few of them, but the inverse is generally true. Humans getting coccidiosis at ALL is rare, and generally only in people with deficient immune systems, like those of the elderly, and AIDS patients, although fetuses exposed to toxoplasma in utero can (rarely) have problems. You could, theoretically, if you have AIDS or are 100 years old, catch a coccidial infection from eating raw chicken or drinking water that your chicken has pooped in. Don't do those things, and you can kiss your chickens as much as you want
