I just went down to check on my chickens, and one of my only laying hens has some sort of fluid leaking from her chest area. This is my first time with chickens and I am really worried abou her. She's a BSL just over 5 months old. She appears to be fine otherwise. She did tuck her head toward the area and was messing with it a little bit. I picked her up and was looking at the area and all her feathers are saturated and it looked strange to me? It almost looks like there's a smal hole there. Any idea what might be wrong with her?! I'm freaking out a bit.
