My small flock has recently been attacked twice by next doors dog. It killed two and badly injured another. I usually free range them all day long in my 2 acre garden but because of this threat, I am forced to keep them in their run until the fence is repaired and the dog is contained. (A date for which is still outstanding) What were the most delicious, rich tasting eggs have become pale and completely tasteless, it's really depressing. What can I do to improve the eggs until my girls are able to roam free again? I feed them on a mix of grains, corn and layers pellets.
