in 5 days try worming her with zemectrin gold, it will get what safeguard has missed- there are some tapes that safeguard wound get- found that out recently- can you get a flashlight and look down her throat? am wondering if she may have canker??My wheezing hen is neither improving or getting worse. I wormed her with safeguard maybe 5 days ago. I thought I felt a hard knot in her throat, gave her some EVOO and massaged it a bit, she didn't like that very much. She seemed stressed in the garage so put her back in the coop.. Caught her eating feed this evening. I hate to prolong the inevitable if she's suffering but also hate to not give her a chance, ugh.
