One of my chicks has a little sore on the bum. It is under the vent and off to the right. I would say it's more on the "butt cheek" if they have one.
They were hatched on May 26th. I washed it today with a paper towel and it had a ton of yellow. I have no idea what is up with the yellow. I put some betadine on it and watched it today. There seems to be more yellow forming around it. Once it dried I could see it was open a tiny bit. Could it be the yolk sac?
Can anyone help me out here? I would rather nip it in the bud before it gets worse.
TIA
