I don't intend to sniff my chickens, but they like to cuddle with me in the evenings before they go to roost. Lilly, the cuddliest of them is always on my upper chest, under my chin. She snuggles her neck against my neck and its really sweet. Sometimes, she puts her head in front of my nose and breathes out... Its always warm and doesn't really smell like anything, but I think it is so cute. My roo sits on the top of the chair and whistles in my ear. He likes to snuggle his neck next to my neck, too and sometimes his 'whistle' is in front of my nose. Same for him; really warm but not really a smell...
