I got home today to my 3 silkie hens to find a red-ish dropping with stringy things in it. I couldn't tell for sure if they were worms or just a strange poop. I couldn't take a picture of it because I didn't find my camera in time. My girls seem fine, if anything they might be a slight bit lethargic (but not noticeably). I've seen the poop chart and I think that what I saw was probably worms, but I could be wrong.
I was wondering, what type of de-wormer should I buy? I won't be able to buy anything over $10-$11, and the only store I have access to find it is Tractor Supply. These are the two I had in mind, but what do you think?
