I've got it easy: one male, one female. I might be able to find out the male's line, as he's from a good, recognized breeder (CJWaldon). The female is from an eBay egg and I no longer have contact info for the seller.
So my Cream Legbars are officially (ahem, drumroll please)
The Grayfeather Line, because I am going to name my future breeding operation (my husband will bust a gut laughing at this) Grayfeather. I can't wait to order some custom-printed pencils. ;-)
Now if only my pullet will LAY AN EGG, the slacker!
