can I get your recipe,and explain fermenting their feed please(process) can you pm me?I've hatched pullet eggs before. The chicks are usually smaller than normal. If you want normal sized chicks, wait a while.
I wouldn't worry about hatching eggs from a bird that's been wormed. I wouldn't eat an egg from one.
I add ground pumpkin seeds, garlic powder, and cayenne powder to my chickens fermented feed. It does nothing to the taste of the eggs and will make the chickens body inhospitable to worms and disease. When a chicken eats fermented feed, a greater proportion of protein becomes available to the bird during digestion. They eat less and put on weight faster. This is my experience.
