I have an approximately 1 year old Black Sumatra hen that had bubbles coming out of her beak this morning(the holes in the beak) when I let her out of the coop. Her eyes look fine and there is no sneezing. She is eating, looks VERY healthy, was scratching around outside...everything else appears normal and none of the other birds have any symptoms at all. I feed them a very healthy diet, they are kept inside a coop every night with pine shavings/hay on the floor. I am in full on panic mode, but don't want to jump the gun and start antibiotics if it could be something as simple as she drank too much water and it backed up in her beak. I also, however don't want to wait in case it is something contagious. I have her isolated right now, just in case. Any thoughts would be appreciated!
