I have two new hens. They are both a year old. I have had them almost two weeks now. One of them layed a good egg a few days after I got them and one of them is laying eggs about every 4 days with a very thin shell and they break right away. While I would like to have the eggs I am more worried about the well being of the chickens. Should I be concerned? Should I feed them something special? The breeder I got them from fed them an unusual diet They fed all their birds peanut butter sandwiches, shredded kale,cabbage and chopped up hard boiled eggs. That was their bedtime snack. At first I thought it was due to the stress of being moved and getting used to a new home. They seem to have adjusted just fine. They do free range so they may be laying somewhere and I have not found them yet. I am planning on fencing in a large portion of the yard for them so they can have the best of both, free range space and safety of the enclosure. I have half the fence up and will get the rest done this week. Hopefully that will narrow the search zone a little and I might find something. My other two hens are 16 weeks and not quite ready to lay yet. Should I be worried or just keep looking?
