Four of my six hens have been laying for about a week and a half now. I have gotten 4 eggs a day, but one once had a peck hole in it. I threw it out and noticed that there was no yolk. I have been getting 3 eggs a day for the past 2 days, but the eggs and nesting material have been covered in a clear, sticky liquid. I suspect that one of the hens is not developing any shell at all, as I have not found any shell fragments. They are still eating Purina start and grow because I have some left over. As soon as it is gone, I will switch them to layena. Any thoughts on this sticky matter?
