I was buying pine wood shavings in a bale for $6 from a feed mill. These were low dust, smelled wonderful and really absorbed well. I realized that I needed more, but it was Sunday and the feed mill was closed. So, I went to the Tractor Supply where I knew they have pine shavings in a bale, got one for $6.75 and put it in the brooder. In one day I could tell the difference with it being wet, some ammonia smell, lots of moisture pooling on the floor of the brooder. The second day was worse and I kept adding more shavings and stirring. The third day I emptied it and started with more fresh and kept the chicks outside for several hours. It began all over again and they are right at an open window with good ventilation. I bought Stall Dry and that helped but, boy, have I cursed those shavings. It's clear that not all pine shavings are created alike. Has anyone else had issues with different brands of pine shavings? I'm heading back to the feed mill on Monday.
