Why are my yokes not as yellow??

[Ericasl]

I have noticed my hens yokes are not as yellow as they use to be. I have not changed there diet. They are also getting veggies from the garden. Is it the heat?? It has been 90 ++ for weeks now, could it just be the stress of the heat, or am I doing something wrong??

Nope, you aren't doing anything wrong....the diet changes from season to season if they free range. Beta carotine creates the orange color in the yolk, and that can change with new growth of grass and plants etc.... no rain, no new growth, and lesser protein also.
