I ordered 9 White Legbar hatching eggs from Rising Pheonix Farms and I was impressed with the egg color and packing method. Not a single crack on the eggs and I got sent 3 extra eggs (1 WLB and 2 BCM). 2 eggs had saddled air cells, but that's to be expected from traveling cross-country (South Carolina to Washington). They do Cream and Opal Legbars along with the Whites.

I have roosters from this line and I love them, but I have never personally ordered from them.

Are you looking for quality legbars, true cream legbars, or just legbars (as in you would be fine with non-standard stock and golden crele legbars)? Sadly, many "breeders" breeding "cream" legbars actually have golden creles or cream splits. Nothing wrong with golden crele, but a good breeder wouldn't sell GC as cream. These same breeders will also advertise legbars as "crested" cream legbars or "creme" legbars.
A good breeder should know the SOP, and the correct name (Cream Legbar -- no crested or misspelling). For true cream, legbar hens should have whitish hackles and roosters should have whitish hackles and saddles, possibly faint golden color (no rich gold!).
If you are just looking to have legbars, any NPIP breeder is good.
Good luck with finding and hatching your legbars, they are a great breed to have!
