What?! That's BS! I would fight that so hard. I'm pretty sure that is illegal. Don't just back down on that, I would fight hard to get that money back or at LEAST to have them give you extra liver of the same dollar value. They can't sell you a product and then not provide the product...that's not right, and I'm sure it's not legal!
As for the taurine, definitely order some as soon as you can. Are there any Asian markets or Halal markets in your area? Those are really good sources for the more unusual meats.
Turkey and chicken do count as different proteins. I like to see two non-poultry proteins in the mix if possible though. Beef is great for vitamin B content. Poultry is great, I buy whole birds and chop them up into servings to freeze. A lot more cost effective that way. More prep work, but worth saving a few bucks. Great edible bones too.
Here's a chart I made up for a feeding schedule...does this look about right? I tailored it a bit for my ferrets. The 'other' category means other types of muscle meat. The 'chicken' category is all bone-in meat.
The chart isn't showing up for me. For bone-in meats they should ideally have more than just chicken. Cornish game hens are a great bone source, turkey bones, duck bones (the larger turkey and duck bones will need to be broken), and some small pork bones are all good bone-in options.
Okay, now it is showing up. The heart and organ will be good, but that menu is too light on bone. I count 6 meals containing edible bone. They should have 7-9 bone-in meals each week. And of course we are still working on the variety. I would try beef next, and then some turkey and if you can find it, game hen. Any luck on getting organs? Ideally they should get more than just liver. The organs should be half liver, half other organs such as kidney, brain, spleen, pancreas.
I got a few cornish hens and a whole turkey to feed for this week. That will have more bone for them, too. I also got some liver and the hen and turkey come with all organs and heart.
I'm still having a lot of trouble finding heart of taurine powder. I did find one store that carries the powder....but they're out of it. I asked when it would be coming back and they said it's not a very common item, so it could take weeks. :/
They should get 500mg per day, per ferret. The capsules are nice for this since they are already measured (1000mg capsules, so 1/2 capsule per day per ferret) vs having to buy a sensitive gram scale to weigh out loose powder.
For the liver, they may be resistant at first as it is very strongly flavored. You can try offering them a sliver hand fed and see how they take to it, but don't be surprised if they don't like it. If they do, fantastic! If not, make a soup. Start out with blended meat (I find boneless, skinless chicken breasts to be the easies to work with) and add some liver. Try 2/3 meat 1/3 liver. If they resist, add a little more chicken until they will eat it. Once you have a liver to meat ratio they will eat, give that soup for one meal a day (add some powdered eggshell so they still get enough calcium) and gradually increase the amount of liver and decrease the amount of muscle meat. Gradually make the soup thicker by addin less water too. When you get them up to 1/2 liver soup, cut back to 4 soup meals a week. We will continue to work them up to full liver from there. Try the soup out and let me know how the first run goes!
They have no problem eating liver, it was one of the first raw foods I introduced. Lou in particular LOVES it. If I give him an option between liver and muscle meat, he'll chose the liver for sure. That almost seems kind of weird to me, but hey, as long as he likes it!
