After losing most of my new flock to what the diagnostic lab called Marek's, I realized they couldn't be right! They are too old and are already laying. What I did find out is that I started feeding laying mash way too early and that could be causing all their problems. I thought we were through (6 out of 10 are dead) and today there's yet another one stumbling around. Bless her, she stumbled right into the laying box and laid an egg. Now she can hardly walk. Is there something I can do to counteract this overdose in calcium? I feel so awful, I just couldn't figure out how to keep them out of the other birds food.
