I have an EE who lays soft shelled eggs. One got broken inside and I had to manually pull the shell out. She then went into a short molt, and did lay another egg for like 3 weeks. She laid a few hard eggs and then I started finding yolks in the coop, under the roost pole again. The she broke another soft egg inside, this time the shell did not come out, she seemed not herself for. Few day and then was better. Now the molt thing again. She eats and everything else normal. My others chickens have been treated for lice fora while now, and I have been treating her as well, even though I never see the lice or eggs on her. Could it be the pesticides? I have oyster shell in the fed and as free choice. I also have a sex link that stopped laying all together. I got her from someone, is it possible she is just older than suspected? She was laying wrinkly looking eggs, her eggs were Always a little strange. Please help!
