i bought some and have them in the bator at a friends because i lost my patience.
BUT i have a blue roo over black hens. the eggs look fertile when cracked. first batch didn't grow, have batch 2 and 3 in there now. ladybug4u is bating them for me. she can't understand why the first batch didn't grow, but we're trying. if batch 2 or 3 starts, i can bring you some. i get 1 egg a day out of 2 hens (which tells me that hen 2 has a hiding space i dont know about yet) thinking of making them their own pen so they cant hide eggs on me instead of letting them free range
