Did i make a big no-no mistake?? The bad says wood shaving, and nothing else. Ive been using this for my day old chicks since they arrived and up to now, and theyre 7 weeks old. Lmao.. it was so obvs they were pine shavings snice i noticed a heavy woody perfume fume from it, but i didnt give it much attention because it didnt seem to be hurting my chicks EXTERNALLY..I didnt think about the internal damage.. Will be chickens get a respiratory disease in the future??
