This is s great post, thank you very much.Well, if they eat it all then they get the same amount of each thing no matter what form it is in as it goes between their teeth.
A cooler could work. I might freeze it in meal size portions each in a different freezer bag before freezing it. thawing liver juice in a cooler is .... unpleasant....you may ask how I know that too). We didn't camp but we regularily visited family a 12 hr drive away.
Then you wouldn't need to leave space for ice. How do you keep the chopped liver from spoiling when you go camping?
Only food for thought, no push intended, but grower or layer or whatever is really important for chickens. They will certainly pick out what they like otherwise. And they usually aren't fed individually so whoever picks first gets one part and the last to eat gets something quite different. Likely smaller bodies means less ability to store nutrients so less flexibility in the composition of any given meal is more important. On the rawfeeders group, one of the most common things said was "balance over time." There is almost always more than one way to do something well. Balance in every mouthful works well. It isn't the only thing that works well.
I think Ember and sorry, didn't remember the other dog's name, are both very lucky.

Ps. Ember and Comet are their names, thank you very much!
