Question: Besides calcium, do you feed your chicken only growing fodder? If not, what is the mass ratio between growing fodder and commercial chicken feed? Do your chicken lay well?
i don't feed additonal calcium. I add chia (or alfalfa/lucerne) to the fodder mix. It is naturally high in protein and calcium. My chickens also free range so get a good range of bugs (mainly dung beetles at the moment) and other goodies. There are only three things that stop my chickens from laying - excesive heat, moulting and going broody.
