I have 7 backyard chickens all about 1.5 yrs old and they are doing wonderful! Even now in January I am getting a consistant egg production of 5 - 7 eggs a day. Today, however, there was something strange. I got 7 eggs but one was a soft egg ... not transparent but certainly a cream color and the 'shell' was almost rubbery. what is going on? I feed them layer pellets along with sunflower and flax seed and leftovers from the kitchen. also make them oatmeal on cold winter mornings. Is there something missing? Was this a once in awhile happening or is it something I should worry about? Thanks for all your help!
