2 weeks ago, i brought home some new pullets. 2 polish, 3 silkies, and a silver laced wyandotte. We have a flock of 10 birds, a few auracaunas (sp?), sex link, comets, australorp. oh, and a peacock who thinks he is a silkie Anyway, almost immediately we noticed the polish did not seem as lively as the other pullets, but I have never had them so I wasn't sure if they were more quiet and sedentary by nature. I separated them by themselves anyway, but they would not eat, never got more active, but never had any other symptoms. They finally seemed to be turning a corner - they would stand up - next morning, boom, both were dead. The other pullets never had issues, and were put in with the rest of the flock. about 2 days ago, I noticed a comet hen was sneezing. She was like that for a day , now she just has this persistant very slight wheeze when she breathes. Next my favorite girl started the same way - sneezing for a day, progressing to a very slight wheeze for 2 days now. They are still laying, eating, walking around - only other symptom is the comet has one eye that appears to be slightly swollen. this morning when the girls went out (they are free range all day) my son noticed one of the silkie pullets did not seem well. Within hours she was collapsed on the ground, difficulty breathing, drooling, and her nostrils (?) were clogged. I cleaned off her crusted beak, (which had no odor) but she was bubbling clear liquid from her mouth and nostrils when she breathed, and was twisting her neck to try to breathe better. Gape worm seemed like a good possibility, I had actually just bought wormer because I noticed worms in some droppings. I went out to the coop to get the wormer, and by the time I got back she was dead I am going to worm the rest of them, but is there anything else I should do? Does this sound like gape worm to everyone? Or something else? Any help is appreciated!!!
