This week Elaine at Sunny Simple Life brought up an interesting fact... raw pumpkin seeds can be used as a natural wormer in chickens. I had never heard this, but always looking for a good holistic remedy, I looked into this a bit and seems a lot of people put stock in this tasty treatment. According to the posts I read, pumpkin seeds are coated in a naturally occurring chemical that paralyzes the worms so the chicken can then expel them (some feel you need to follow up with buttermilk to help with the elimination). You can read more about how this works at The Backyard Chicken Coop. At the very least, your hens will get a real tasty treat without nasty side effects!
Thanks for sharing Elaine! Hope your flock continues to flourish!
