I have 2 Wheaten Ameraucana's who lay smallish blue eggs. For the past 3 days now they have not laid. Should I be worried? They are on an organic pellet layer feed, they get probiotics and electrolytes daily in their water, treats are minimal...occasional watermelon and cantaloupe rinds, live meal worms or whole oats. They do get fermented feed on occasion which I heard was good for them. They are acting normal and eat and drink well. Nothing out of the ordinary that I have noticed. Could they just be taking a break from laying?
