Pros: fluffy, caught easier, good for cooler weather, bantam silkies seem to be VERY protective of their hens, and they get broody alot(if you like that)
Cons: easier prey, some of them act sort of mental (waddles, gets lost without the rooster), gets broody alot (if you don't like that)
I've had nice experiences with them. They look and feel great. Sometimes, if you want them to see properly you'll have to trim the "tophat" feathers from around their eyes. They have funny voices! With one of my silkies she's sort of mental, we call her Airhead. She waddles, gets lost really easy, and she "cries" for her rooster (bawking). Also, they get insanely broody easy. My other silkie hen sat on a nest, hatched bits, we took it to put with our other just-bought ones, she went right back, and we couldn't get her off for a month or two until she finally gave up after us tossing her out of the coop during the day. She was very stubborn!
