My chicken has been inside for about 6 days because her sour-now impacted crop won't go away. she's been given antibiotic medicine which got rid of the sourness but every morning she still has a really hard clump in her crop! i haven't fed her any solid food and have given her oil regularly but it won't move. I can't make her throw it up either even after it has been softened. it seems like she just passes the water through but the clump won't move.she has lost a lot of weight now and is extremely depressed and now I don't know if i should let her out and hope it solves itself, it's just not moving, please help!
