Hello all. Some of you may remember I posted Thursday about a 1 week old chick named Fern who was lethargic and seemingly dying. She is my first chick ever, so of course I panicked and began researching right away as well as posted on this forum and got some much needed help from this community. I first treated for cocci, but this didnt seem to work and I kept researching. It's been almost 4 days now, and I'm almost certain Fern has a crop-related issue, but I'm not sure if it is sour or impacted crop. My first geuss would be impacted crop, since Fern likes to eat the pine shaving bedding I have in her box. She is lethargic and always sleepy, but she does eat and drink a little each day. For the first day I didnt treat for a crop issue because I thought it was corid, but on the second day I treated for a crop issue by using olive oil. The next day, she was much better! I could tell definite improvement. I didnt give her as much oil that day. The day after that she was back to being sluggish :/. I dont want to give up on her yet. I'm going to keep treating for impacted crop and hopefully see some improvement, but should I be doing something different or treat for both impacted and sour crop? Any advice would be appreciated. Thank you for reading all this.
