Hi! We have 4 chickens and one of them just started laying almost 2 weeks ago (yay!). All 4 chickens are 17 weeks old right now. Right after we got our first egg, she laid 2 more normal eggs, then 3 shell-less eggs. I switched completely to layer food and offered crushed oyster shell after the first 2 eggs to make sure she has enough calcium, but now I’m a little concerned that the other 3 chickens who aren’t laying are eating layer food. My Delaware chicken probably won’t start laying for at least another month and a half. I’ve read mixed suggestions, so now I have 2 smaller feeders- 1 with layer food, 1 with grower, and oyster shell. But of course I can’t control which of the foods they are eating, and this morning I got another shell-less egg so I’m concerned the laying hen is eating grower food, but at the same time I’m concerned about my hen who won’t lay for a while eating food with too much calcium. The laying hen is a Novogen, the other three are 2 barred rock and 1 Delaware. Any suggestions will be greatly appreciated!
