Hey y'all, So the short version of my story is I have a 3-4 month old (tiny) pullet who is a mutt (maybe mixed with a production red) who has been very sick for almost a week now. I recently had another cochin pullet that I got at the same time as her die with similar symptoms. She is very lethargic and sneezing, has gurgling/crackly lung sounds in inspiration, and I think has/had tapeworm. We noticed a couple days ago what we think was a tapeworm segment in her poop... https://www.backyardchickens.com/t/1139763/help-quick-this-poor-chicken-cant-catch-a-break-updated We treated with cat tapeworm wormer (cause that is all we could get at the time) and she seemed *slightly* better. She is still eating and drinking and her poop looks better. We started injectable Tylan 50 the next day. 0.5cc injected into her breast muscle. I think her respiratory symptoms have improved a little. But today I noticed that she was back to being extremely lethargic again. So my question(s) is: Is there any sort of drug interaction between the Tylan 50 and the praziquantel (wormer)? Maybe the Tylan is making the wormer not work? Maybe we dosed the wormer wrong? Also, How long does Tylan take to kick in before they are better? And same question about the wormer for tapeworm? Should I redoes after shes done with the Tylan? Sorry for the rambling. Thanks for the help!
