I am going to get about 8 hens free from a friend. She's giving them up because they insist on drinking gross algae water instead of from their waterer because that's what they're used to. Soooo, their eggs have a gross, algae like taste. They live in an area devoid of sun. I will have to keep them separate from my hens until all of the nasty eggs are gone. The question is....how long until all the nasty eggs cycle out?
