Hi All, I have a 7mo old Silkie hen, Mango, who started laying about a month ago. This morning we noticed her acting lethargic so we brought her inside and gave her some poultry cell. While holding her, she passed a shell less egg. This is the second time she’s done this. She seemed to be straining a lot to pass the egg. She still seems a little tired, but is walking around pecking for bugs now. We give them crushed egg shell from time to time for calcium. Anyone else ever have this or know what this means?
