I then ran that through the blender until it was smooth enough that my ferrets ate it. It's good to work them up to lumpy gravy, but I find that it has to be a very gradual thing. Raw skin and fat do not blend well in my blender. Some people have suggested using poultry shears to cut them into tiny chunks. After cooking, run everything through the blender again, and the cooked skin seems to blend up just fine.
Poultry shears are a great way to cut the chicken into hunks.
They even handle the smaller bones easily. Bob suggests using a hammer to smash the big bones into small pieces, but I haven't tried it. Now they all love it and eat it eagerly. A syringe would work, too, but be really careful not to squirt anything down the fuzzy's throat. One of my ferrets took probably seven or eight times before she decided it was yummy.
