yolks break easily

[Robert1959]

We are experiencing yolks that went from almost can't break ..to breaks easily when the shell is broken ? I have heard its a outside heat problem [?] In have oyster shell out for them but they seem to ignore it they are total free range , but are given layer pellets and vitamin water several times a week . also once in a while a yolk will be milky totally stumped on these things

You might try their own egg shells chushed insted of oyster shell. just rince out the egg shell, put them in an oven to dry out (about a 400 degree preheat) and crush them all up small for them. Mine eat this over Oyster shell.
