Why are we getting firm yolks in our eggs with our free range chooks?

Question

they eat shellgrit, wheat, green pick, food scraps, laying pellots. we think it might be because of the high protein in the wheat. Please help

Answer 1

Mainly because your chicks are healthy and well cared for. Fresh eggs are always better too. Who knows how old the one's you get in the store are.  

Answer 2

I think that what you are seeing is what a more or less wild diet does for eggs.  The free range are eating meat also.
