My chickens are molting right now. They look bad but still healthy. I have one she eats and does everything normal but this morning while watching her eat watermelon I kept hearing this bubbling sound for lack of a better word. I have separated her and wondering what I should give her. Like I said she is in molt but acting like usual. Nothings coming out of her nose. Wondering if she might be getting some kinda of respiratory illness. I won’t take her to vet. Expensive and it takes a good 10 days before we get the results. I give them vitamins, fruit, meal worms, cracked corn. Suggestion please.
