A fungal lung infection from inhaled Aspergillus mold spores in damp bedding or moldy feed. Often hits chicks in brooders. No discharge, unlike bacterial respiratory disease.

Remove the moldy source immediately and clean the brooder. Move surviving birds to fresh, dry bedding. Antifungals exist but treatment is hard. Supportive care: warmth, hydration, nutrition. Severely affected birds rarely recover.
Prevention
Keep bedding bone dry. Throw out musty or clumped feed. Never use moldy hay or straw. Clean brooders between batches. Avoid wood shavings that are damp or dusty.
