One of our hens just laid her first egg. (https://www.backyardchickens.com/forum/viewtopic.php?pid=130133) It is a double/softshell. Our hens obviously need more calcium. I know everyone says to offer oyster shell free choice, but I do not know what type of feeder to use. We have a feeder for the layer pellets, (a white cylinder with an open top over a red tray) but it seems like maybe we should use a different kind for the oyster shell. I know we should not mix it in with the food, but how do we get them to want to eat it? Will they just see it and think it looks delicious? How long after starting the oyster shells do the egg shells start to harden up? Sorry to sound like such a dork, but Barg is wigging out over this first egg, and I want to keep it from happening again.
