Here's another Blue Silver Pullet that caught my eye. Not sure if it's possible to put lacing in the breast of the females or not but I like the way this one is looking. So I figure there is only one way to find out and that is to try.
The APA standard seems to be silent on the subject of female breast coloring in Silvers. But here is a quote from Bantam Standard (page 248 of my 2011 edition). Under color of female silver:
Breast: Salmon, shading to gray under body, free from shafting. Then, on page 249, defects are listed. Quote: "Reddish cast in female secondaries - lacing or frostiness in female breast feathers.
So it appears the object would be to produce as even a salmon color as possible in the female breast feathers. That has always been my understanding, but I had to look it up to be sure.
