My young chickens started laying nicely. Normal eggs in the laying boxes but now I am getting more rubber super thin eggs than regular ones. I am giving them lay feed and even putting oyster shell in the food to help but I am still getting these. One thing is it has been super hot here so not sure if this is affecting them. Can that cause these eggs? Since they are new layers could I have one that just has something wrong with it and will always lay these eggs that are always broken as they are so thin. Will this work itself out. It has been happening for about a week now.
