Hello! New chicken owner here. Our olive egger Belle is 9 months, and yet has never laid an egg. Her feathers look a bit rough and her comb is a sort of grayish pink. She has greenish yellow diarrhea that sticks horribly to her vent, we've had to trim those feathers to make sure they don't paste up. At first we thought Belle was infertile, but the constant diarrhea and her appearance have us concerned. Any help would be greatly appreciated!
