So my gfs mom brought up a good question to me today she said " see the lil white ones, well the ones that are almost all white" I said yeah? She said where'd they come from, I asked what do you mean... She said you don't have any full grown bird with white one them... Or atleast not a lot of white on them. one of my Roos has silver/white on his neck but not a lot so when I became aware of this I became puzzled. Can anyone answer this canundrom for me
