I got my 3 day old chicks on March the 13'th. RIRs and white leghorns. Still no eggs. They were free-range until a few days ago. I am feeding them Dumor layer feed. They squat and the roosters are constantly breeding them. I put some in one pen with the roosters and some in another with just hens, just in case there is an egg-eater. Still no eggs. I KNOW I have heard egg songs but cannot find eggs. This is when they were free-ranging. So I penned them up because of having to hunt for eggs and predators. But still, I can find NO eggs. Mom's are 1 month younger than mine and she already has 2 eggs. It is hotter where she is too. Are they eating their eggs? I search really hard for pieces of shell and even in their poo. I can't find any evidence of broken shells. We check several times a day too. The chickens are from McMurray Hatchery so I figured they'd lay faster. sigh. I'm gonna buy a bag of oyster shells and see if that helps. They're fat, healthy, sleek, and all look so nice and fluffy-bottomed.
