Our chicken Bubbles has been having some problems over the past few weeks. When winter started all of our girls started drinking a lot of water, especially her. We thought it was normal and her "food sack" as my kids like to call it was abnormally giant and full of water. Now it's been like that everyday. Its about the size of a coconut and her body is very small. When you pick her up she is very light and you can see that her "food sack" is just extremely expanded and full of water. I've stood outside and watched her eat the chicken food so I know that she does eat but her "food sack" is becoming worrisome. I don't know if it's an infection or she just always drinks water (I don't think she could keep it up to the coconut size 24/7 even if she drank ALOT of water). I also forgot to mention that when you pick her up then set her down she throws up or even she falls down sometimes and throws up. It smells horrible and definitely not healthy. I love my chickens with all my heart and I dont want one of them to die Please help! I don't know what to do!
