I have a Golden sex link that typically has a bright red comb. Lately her comb has turned orange (pale) and she is sluggish. I often find her laying down in the middle of the yard with her eyes closed. My wife and I are going to isolate her to check her poo, food consumption and if she is laying or not but based off of what I’ve said and the level of her sickness, does it sound like we can help her or do we need to go to the vet? My wife and I are incredibly tight on money right now and can’t afford a $250 vet bill. Is my chicken too sick for me to cure?
