I can't seem to crack any of my bantam cochins eggs without breaking the yolk. I don't know if its me or if the yolks are weaker than the other girl's eggs. Her eggs are pretty small and the shell and that inner membrane are pretty tough so I could just be too rough when I am breaking them but I didn't used to have that problem. Is that a sign of her needing something? Or a sign that she has enough calcium since her shells are so thick? Also, her shells are almost completely white with a tinge of pink. I saw another thread about this so I know I am not alone, but I don't know if this is a sign of a lack of something also.
