I need help! I bought 4 peachicks from a reputable breeder and they survived for about 4 months until yesterday. I went out to feed and water the birds and saw that the male was looking lethargic. He was moping around and wasn't acting like his normal skiddish self. I picked him up and he was very skinny, I could feel all of his bones. I didn't even notice a change in his health until yesterday. So I mixed up some antibiotics with their water and put some down his throat for an extra boost. So I went about my business. I went back to check on the bird and he was DEAD! I have three left, but I fear for their health. I'm crossing my fingers! Do you think it is better to buy adult birds or to buy young chicks and is there anything I can do to help with their survival?
