About one month and one week ago I found a shell-less egg in my nesting box. It had no inner/outer membrane, only a yolk and a white. At first I though that one of my chickens just cracked the egg, but no shell was in sight. Three weeks from now, it happened again. I had also been noticing that my chickens eggs were becoming weaker, so a couple of weeks ago I began feeding them oyster shell. A week ago, I noticed that there was an embryo-like thing inside the fecal matter underneath the roosts. This morning, I found one of my Barred Plymouth Rocks dead (assumingly from a sickness of some kind).
. What sickness did this chicken have? Is it contagious? What should I do? If you have any questions I will be willing to answer. Thank you for your help.
P.S. The chickens are one year old.
