My 6 girls are 21 weeks old and at least some have been laying for about a week. I had switched them to Flock Raiser after finishing their first big bag of Starter/Grower since I wanted them off medicated feed. So far their eggs have had nice hard shells, although they are still small. I've been giving them baked and smashed up egg shells for about a week or so. I need to go buy more feed and I'm trying to decide if I should stick w/ Flock Raiser and add oyster shell. They get A LOT of fruit/veggie scraps from us each day and are able to free range in our yard for about 6 hours/day. I was thinking that with using the higher protein Flock Raiser they'd still be getting adequate protein even with all the fruits and veggies. Or should I jut go with the Layena? If so do I still need oyster shells. What do you think?
