Please help with some advice. Here's my 13 week old maran originally from MPC. Noticed her being lethargic 2 days ago. Yesterday we isolated her with water only. I thought it may be impacted crop but after trying to vomit her all that came up was water. Here's a pic of her and her poop which is yellow and watery. She appears to be nearly gone. I did not immunize for mareks.
