When the baby chicks were little, I could not believe the amount of dust that they generated. I had no idea why and initially chalked it up to the brooder’s bedding. However, I noticed that as they grew in size so did the dust. I was still using the same amount of pine shavings in the brooder for bedding, so why more dust? It surely could not be solely from the pine shavings and I was right. It was from the chickens themselves. The majority of the dust was coming from them.
