I currently have 5 red sex hens (had seven only a month ago). I am so sad about the two that died and I think both died from egg yolk peritonitis which is incurable and prone to these type of hens. They are 2 years 10 months old. I am lucky to get 2 eggs a week from them. I have been feeding them Purina Layena Feed for years now. Here is a link to the product- http://poultry.purinamills.com/OURPRODUCTS/Products/Layena/default.aspx
notice the protein and calcium is 16%. When I do get my 2 eggs a week, the shells are weak. I do offer free choice oyster shell but never see them eating any of it(or maybe a few are and I'm not see it), I also offer free choice grit and I see them eating that occasionally. I don't know who or how many of my hens is/are laying the eggs so will try to keep an eye open.
Should I change the feed? What percentage protein and calcium should I feed these hens? Thanks. I have a Tractor Supply store nearby.
