I have a 5 week old chick that I noticed was breathing heavy this morning. Otherwise acting normally. Later this afternoon I was with the birds and I noticed that the chick was having some bloody/watery poops. I separated him/her into a different brooder so I could see what was going on. The chick is having basically red/watery poops with what I noticed were a few pieces of what look like undigested meal worm in it. No 'poop' material, just pink water with the occasional worm piece. I offer grit (sprinkled in their feed), they get a pinch or so of dried mealworms once a day. They are on medicated chick starter. The chick is not lethargic yet but I am not sure what else I should be doing for it. She is separated right now with food/water but she seems more stressed away from her buddies. Any advice would be appreciated. Thanks so much.
