3 25kg bags of pellets per year, 25€ each - 75€
12 bales of hay, 4€ each, 48€
One bag of barley, 15€
4 bags of wood stove pellets as litter, 5€ each,- 20€
Some oatmeal.
About 180€ per year for food.
That's pretty much it. For 6-25 rabbits. (Yesterday I had 15, now it's a bunch more, Chantal gave me a surprise). I feed mostly fresh forage whenever available, , let them graze whenever feasable, make a third of the hay I need myself.
In winter I feed hay, trees, topinambur, apples, and if I can get it cheaply carrots and cabbage (that would be another 30€ maybe).
Well, and then there are vet costs. The most I paid was 300€ for an emergency spay of a 7yo doe with a kit stuck all night after a surprise litter (I get a too many of those...), normally a vet visit is 50-70€ and happens once or twice a year.
