I had all my silkies running together until about 2 months ago. Then a month ago, I let the white rooster in the pen with the girls for a week before I could get the dividers built to seperate the colors. (I had 3 buff, 2 blue/splash, 2 white hens in the pen). I then seperated all by color with their respective colored roosters. So, technically, they have been seperated with the correct mates will be three weeks on Sunday. Should I go till 4 weeks before setting any eggs? I know that buff is doing his job and so is the splash so I would think that they would be fertile by him. What do you guys think?
