My 3- one year old hens I adopted last week have been laying. The first few eggs were "normal" today I had one with a soft spot and it did not feel right after I cracked it to look inside the shell was paper thin. Question#1 are those eggs ok to eat? #2 is this a transition egg from the move? I have oyster shell out and kept them on the same food. Other ideas? and yippee they found the nesting boxes!!!!
