Last night I noticed that my 2 1/2 week old Blue Splash Marans was very lethargic and sitting by herself. I initially thought that she had a problem with her legs and immediately put niacin with electrolytes and probiotics in their water . They usually get ACV in the water. She did drink water this morning but I didn’t see her eat. She had a full crop last night. She also had pasty butt within a few days from arrival from the hatchery and I cleaned it with warm water and put olive oil by her vent. At times she is standing tall moving her vent up and down like she’s trying to poop. I just gave her some water and molasses and a little bit of olive oil and she did poop but she’s still sitting by herself. What else can I do for her. I took a video of her after I gave her the molasses and olive oil so she wasn’t too happy with me. Thank you in advance for your help.
