Alright. Chicks just arrived this morning. These chicks were vaccinated for Coccidiosis and Mareks. Two arrived dead in box, one passed away in my hand a little later, and then I found this one struggling and found this. I'm not sure what this is. I do believe it is coming from her vent cause she has more there then when I first caught it. I have seperated her from the others, so they don't mess with her. When I picked her up the first time she had mucus come out of her beak! Any advice or thoughts! HELP! Thanks in advance!
