I have a question for all the chick experts. We have nine chicks. One of them has had the runs since we brought it home. It doesn't look sick, and is actually one of the spunkiest chicks in the brooder. I keep checking her vent and it's not pasted up. Should I be concerned? Is it just the ceacal poo? Almost looks like watery peanut butter. I don't see blood. I haven't seen any solid-ish poops come out of her though. Everyone else's poo is normal. They are on a mix of medicated chick feed and 7-grrain cereal (thanks Chickee!) from the health food store that they LOVE. They also have the vitamin additive in their water. Any input?
