How old is the chick? Is there any chance of injury? Can it walk or stand? The gasping could be pain related or it could be something respiratory. Have there been any other symptoms other than the lethargy? Any wheezing, sneezing, runny nose or diarrhea? Any other chicks with issues? The dust bathing shouldn't have anything at all to do with this. Have any other members of you flock ever had respiratory issues that they have recovered from (and possibly be carriers now)? I wouldn't put the chick back under the momma if you have an alternate heat source. The momma will care for the active birds but probably won't nurse a sick or injured chick back to health. The whole survival of the fittest thing.Okay so I went out this morning and my little hyperactive white silkie is lethargic. Gasping for air, and is holding her wings out. I gave her a bit of poly vi sol and put her back under her mother. The only change I made out there was letting the momma dust bathe. I used wood ash and our normal run sand. Not alot of wood ash. She was fine last evening. THey are in the barn. It got pretty cold last night but they are in with momma. I really want to save her. I don't know what else to do for her. She alomst seems aspirated, and weak from gasping. I have poultry drench and poly vi sol and electrolites in my arsenal. Should I get some kind of antibiotics? I don't want the other chicks getting it too.
