I picked up a tiny one from radio shack but it was 3x more expensive than the one I ordered. Try best buy, circuit city, or another electronics store. They sell them for cooling computers and gaming systems.
I hatched 7 of 9 honas!
(If I keep posting this joke, eventually someone will laugh. :hide)
Have you ever seen one hatch like this?
One other hatched silvery with pink toes, but the other five are very dark.
BYC member @Ron Skekel has those breeds. She's NPIP and ships. I'm not sure on her prices for eggs, but I got my svarthona breed stock from her. Her neiderrheiners are TO DIE FOR. Just gorgeous.
