I suppose you have to wash it out from the chicken juices? Why bother, Pickles would gladly lick it clean.
So many things will do the job. Since it's warm here, I've bought tight netting and made my own mini greenhouse containers... something like this.
It's so warm here, I plant directly into the soil. So far, so good. I'm lazy like that. I thought that was a salad to go at first, very cute! I don't buy very many rotisserie chickens these days, but it's nice to see the containers doing double duty. I love reusing things like that. I store all kinds of things in my empty cat litter buckets. I might use one on the balcony to store my implements, gloves, etc.
The rotisserie chicken container idea looks like it would work well, and a good excuse to buy rotisserie chicken.
