About a week ago my husband threw some mushrooms for the yard in with the chickens . The second he told me (about 10 minutes after he did it) I went down there to take them out, but of course they were gone. Since then my 4 bantam cochins have completely stopped laying and my golden comet is laying about 1/2 as many eggs as she used to... and the yolks are very very pale yellow (almost white when hard boiled). So I went from 4-5 eggs a day down to maybe 1 if I'm lucky. Nothing else changed except the weather which has been quite wet and colder than usual. Could it be from the mushrooms??? If it is will they ever start laying again?
