I am not sure what Excelsior poultry pads are, but I have been using Dri-Bed underpads that they use for humans in the hospital. I had 4 packs of these leftover from when my husband was sick and confined to bed. They work wonderful. Now that the chicks are 7 weeks old they tend to crumple them up a bit. They actually try to dustbathe on them. So I am thinking that the Excelsior poultry pads would work also, and be a lot neater than shavings. I just fold the dirty ones up and toss them in the trash and replace with fresh ones each day.
