Some people might know about a bird i have that i put threads about a while back. The one with the eye problem. She seems to be getting worse and won't eat or drink. Should i cull her? Most of the time she just sits on the bedding, I feel bad just not being able to do anything and letting her slowly get skinnier. I've never culled one of my birds unless it was for freezer camp and i've only done that once because i couldn't do it to any of my other ones. please help
