I recently posted in emergencies and diseases about my one hen that had passed, and my Silkie hen that I thought was sick too. I never got any responses, but fortunately, my Silkie hen seems to be doing ok. My question is, the first day she was acting off, she laid a rubbery shelled egg, the kind that look like a deflated balloon. Well, she has laid one of those for 3 days in a row now. Could this be problematic? All the research I have seen says it is usually because it is a new layer, or not enough calcium. She is not a new layer, about a year old, and has always laid normal eggs up till now. All my hens have 24/7 access to oyster shell, and are on layer feed. (I have notice that I'm not going through the oyster shell as much as I used to, though, for some reason.) In the past, I would find one of these types of eggs from time to time, but not consistantly, like I am now. Any suggestions would be greatly appreciated. Thanks!
