I would need some advice for worming chickens. My hens are around 24 weeks old and I have never wormed them. They started to do a strange movement in the chest area, moving the chest/nest side to side, up and down, quite quickly, and this only at night time while on the roost. It doesn't seem to be a crop problem, I check their crops every morning to make sure they are emptied. My boyfriend gave the vet a call last Friday, and he didn't seem to take us seriously, which is really starting to be frustrating as it is hard to find a vet that treats chickens in my area. As soon as we mention we have only 4 chickens, they make us feel as if we're stupid for calling them and as if we're wasting their time. So anyway, the vet wasn't very helpful, and said it was probably nothing if they are acting fine as usual apart from the strange movement at night. My boyfriend asked if worms could maybe be the cause, but the vet said that chicken don't get worms? what?! I've been reading so much about chickens and I've read everywhere that chickens do get worms. I've read that we can worm our chickens by preventive measure, right? So since my vet says they don't get worms, we can't get some dewormer from them, so I've been searching the web to buy some online. (where I live, we can't get some at the feed store, we have to go through a vet). I found this one on Amazon, I'm wondering if any of you would recommend it? http://www.amazon.ca/Durvet-Rooster...id=1411949183&sr=8-1&keywords=rooster+booster Any advice would be great thank you!
