My mom adopted 2 dogs about 2 months ago, and I saw dog tapeworm segments on their poop prior worming them, and I also saw dead roundworms and/hookworm on their poop after worming them with Valbazen. Some of my chickens knows how to get out of the cage, so there is a high chance that they ingested some roundworm eggs on the grass, even if my mom and I try to poop the dog's feces in the garbage. Some say no, and some say yes. I want a link that confirms, whether or not chickens can get dog roundworms, hookworms, and tapeworm after ingesting eggs and/or intermediate host. The last worm dosage was given to them about 22 days ago, and I didn't see any tapeworm segments after worming them.
