I have a hen that used to be a champion layer.... big flavorful brown eggs. Now her eggs have a runny, watery white, taste bland and are often not laid. (so I thought) Yesterday I went in to find she just laid a soft, broken egg and all the other hens were fighting over the bits!! Oh no!!! I cleaned out the box and their was a lot of egg goo. This hen is atleast 1 yr old, but i just got her in the spring so I am not sure how old she is. She eats the following, same as everyone...... layers mash, chick grower (young birds in same pen), scratch, cracked corn and treats of vegetables. I also periodically put organic apple cider vinegar in their water. The only other thing that is weird is that she eats constantly, like she just cant get enough. I even put some oyster shell in the coop. Could this be some sort of disease? Or could it be because she eats mash and is only eating certain pieces? Should i switch to crumbles?
