I have now 21 chickens and 1 rooster, 5 1/2 months old. They have been laying eggs (no more than 4 per day total) for about three weeks now. The Americana (aka Easter Egg Chicken) died after prolapse from laying an 85 gram egg. We lost a Leghorn to a ruptured ovum as well. According to the vet, the chickens are too young and it is the wrong time of year. We have darkened the coop as much as possible and introduced additional wheat into their diet, although I am unsure of the correct amount I should be feeding. I know to slow egg production for commercial battery chickens, the food is stopped. However, I do not want to starve my chickens. Is there anything further I may do to stop egg production until Spring. Any and all suggestions are welcome. Thanks so much!
