I have a 5 week old golden laced Wyandotte chick. Up until this morning she has been thriving. However, this morning she seemed lethargic and not interested in eating/exploring. She stood off alone for a while and went back under the warmer which is unusual when they’re out in the coop. I massaged her crop and while doing so she regurgitated water. I used a dropper to give a little olive oil as I thought maybe there was something stuck. I isolated her the remainder of the morning so I know this poo is hers. Any thoughts on what could be going on? Thank you!!
