I candeled my eggs yeterday on day 9 and I can see that six of my bought 8 blue standard cochin eggs are fertile and 100% from my own hen Astrid but none of Jinx eggs are fertile. In my previous hatch from three of my own hens 100% was fertile from two hens but none of Jinx's eggs. She doesn't like the rooster but I have seen him trying to do his work. I have cut some duns and feathers away around the genitals to help nature on all my hens and the rooster but obviously it's not enough on Jinx. She is the best lined hen I have and I would realy like to have some babies from her and this rooster. Is there anything I can do to make them a love couple? He is kind of rough with the hens and Jinx is really avoiding him and put her tail feathers between her legs and sit on them when he tries. Any ideas how to solve this?
