x3 on keeping a back up roo. I only hatched 2 males (& 6 females). I sold my extra male with the extra females. When my 6 mo old male died of possible heat stroke, I was so upset, I sold off all my females. I missed having my Bieles all winter! Now I'm finding it much harder to get good eggs. At least I hatched one very sweet female. (Hen Solo is her name.)supposedly they say to build the house first. You can always work on color later. Might think about keeping a second roo for a backup. So maybe the first one for size and the second one for color?
