I was wondering if this is a bad idea. Assuming that the worming is not an urgent thing (in other words, just precautionary, per schedule, or otherwise not a "sick" chicken), is it a bad idea to worm a chicken who is molting since their body is already under stress? Or is it better to wait? Does the answer depend on which wormer you are planning on using? Please note, I am not referring to giving them de, pumpkin or other natural methods, but medicinal wormer.
