My silkie hen has been sick for a little over a month. Lost a lot of weight, constant diarrhea, weak, balance is really off, she stumbles and falls all the time. Her crop will also get really full feeling/looking and if you touch it, even very lightly, she starts spitting out clear liquid. She's about 2 years old. Someone said they thought it could be coccidia so today I started her on corid. But I'm wondering if she might have worms. Does this sound like a worm problem? Should I treat her for that as well as keep giving her corid? And what's a good treatment that can cover all the potential worms in one worming medication? Any advice is much appreciated!
