So I have four females to one male. One of my females was born with what I thought was wry neck. She has never been stunted by the fact that she has it and has been a happy bird. I tried adding in polyvis into their water when she was 3 weeks old but always figured I was too late to help. Now I had my first and second successful hatch. After my first batch was about two weeks old I started to notice one of the chicks necks to start to bend like my females. Now it is 3 weeks old and it is very apparent that it has the same neck. So here is the rub. I started putting polyvis into their water from day one just to avoid this issue. I wonder now is my female just genetically flawed? Should I cull her to prevent this from happening again? I am not sure that the baby hatched was her's its just my guess. What would you do?
