What you have described like raw chicken looking matter could be Mucous plug( Dried off mucous which takes the shape of structure of airways). Have you preserved that chicken looking like matter?
If yes then show it to Pediatician, he will see it and reassure you, at the most he may Advise Chest X ray
and if it shows pneumonia
then Antibiotics and Mucomist ( N Acetyl Cysteine
) Nebulization( it makes the dried secretions wet and helps in removing) will help
Take Good Care
God bless us all
