I have one roo and 11 hens, (not by choice but we like him) all 16 weeks old. I'ts been suggested that we get rid of the roo if I'm only interested in eggs because I will be getting blood spots in my eggs. Is this true? Do you have to candle the eggs if you have a roo if we collect them daily and refrigirate them? Do you candle the eggs without a roo as we plan on selling the extras? Thank you in advance for your help.
