I have 10 hens and a rooster ranging from 9 months to 1 year old. They are fed flock raiser, have plenty of water, get daily oyster shell and a treat mix that consists of scratch feed and mealworms.
One of our EE girls(1 year old) has started laying thin shelled eggs pretty consistently...
I read most of the threads. Got a lot of information. Giving oysters shells,free ranging ,this-that.
I read if excessive its harmful
My question is that what amout is harmfull?
And what happens if they eat excessive calcium?
