I wormed my 8 hens (2-3 years old) for the first time ever yesterday. They've never been wormed before because I've never felt they needed it- I've had fecals run by an avian vet over the years, and they've always come back with negligible parasite loads. However, it's been a long, hard winter here, and I had a couple of girls that seemed a little unthrifty and maybe a little thinner than I'd like. I know I had a mouse problem this winter (all creatures were looking for relief from the cold this year!), and I saw a few mice eating incidents in the past month or so... All that led me to just go ahead and try a deworming cycle. I did a simple deworming with Wazine in their water yesterday, and was planning on following that up with Valbazen in 10 days. However, today I saw a good amount of milky white diarrhea, not coincidentally coming from the two that I have specifically been keeping my eye on for a little weight loss. I did not see any actual worms, just this unpleasant poop: Is this normal after deworming, or a sign something is wrong? Based on egg shell color, I know both of them laid eggs today, so I do not think the milky white stuff is coming from stuck/broken eggs. I have an avian vet in town and would not hesitate to take them in if this is a big red flag after giving Wazine. Also, now I'm questioning whether it was the right decision to deworm at all. Should I take in some fecal samples before following up with another dewormer in 10 days? It's been such a hard winter, I'd hate to think that I've done anything to hurt any of these girls after they've been troopers all winter long.
