My barred rock hen is around 18 weeks old. I have 7 hens now, all getting close to laying. Just no sight of an egg yet. Well, this evening, I reached down and went to pet my barred rock (bc it's funny that she's getting all excited about laying now & squats every time you touch her) and she squatted out a yolk! They are all first time layers & we did have a stressful event occur about 5 days ago where some coons got ahold of 4 of my hens. But should I be worried this broken yolk discharge could cause her to get sick? Or cause peritonitis? It was only a small amount around the size of a half dollar & the hen doesn't act strange at the moment. Just want to make sure I prevent anything that may occur. Thanks!
