Hi, I have a 7 month old silkie and she's never been plump but her breast bone is very prominent when you feel it. She doesn't appear skinny because of her feathers but it doesn't seem normal. She is acting fine. Her poop is normal. She is fed layer pellets among other treats scrambled egg, yogurt, fruit, corn She is housed with 2 japanese bantams that eat like pigs There is a constant supply of food and water. I put ACV in their water every time I change it. I'm at a loss as to what is causing her to be soo skinny. They have all been treated for worms. She seems like a happy chicken except she's too skinny. Is there anything else I can do to fatten her up and make sure she's healthy. There aren't any vets around here that will see a chicken so I will have to treat her myself. I did just recently by a new bag of food and the other two chickens seem to be eating it and have been fine.
