OK...well she didnt do a full molt, she did lose scattered feathers for a week but that has stopped. The egg shells were either multi-colored, multi-textured, huge, or tiny (like the size of a peanut). I've also found a yolk, whites, and a thin broken skin as if the shell never really developed but dont know if it was from this same hen. I have not checked for parasites, will do that as soon as i get home. She is not acting differently, eats and drinks just as she always has...she's the same old girl. This is my first flock and everything has been perfect. This was the first real 'glitch' I've come across and dont know whether to be concerned. I'll check for parasites, and go from there. Thank you for your advice.
