I have found a really thin shelled (paper thin) and miss shaped egg two days in a row now. The egg is also fairly large in size. The first day the shell was so thin the egg broke when layed (which is a concern for starting egg eating). I have 9 hens, 7 laying and none of the other eggs looks this way. They are thick shelled and normal shaped. If anyone has suggestions I would really appreciate your imput. We are new to raising chickens, loving it and worrying about every thing we think may be wrong.
