I have two females in one side of hutch, they dig their pellets out of feeder, wasting most of it.
I've never had this problem with rabbits before.
Mini Rex rabbits

The lady I bought my rabbits from have them just a half a soda bottle full everyday she said if you don't they'll waste a bunch. I have the big meat rabbits.

Try a broader dish to give them some room to push the stuff around, blend in some cheap groats to make em work for it.

Ours get picky at times, usually means they are spoiled (the rabbits,not the pellets), cut the rations and they respond.

feeding to much. they will waste what they don't want to eat.

It's in a small gravity feeder, same one I've used for decades, but these two seem to dig it out for some reason

Move the feeder a little higher if ya can. Are they bred or maybe time to be? Maybe put some chicken wire over the opening of the feeder and throw some chew toys in the cage.

Roast both of them together!!!!

Problem solved!

I'll try going higher, they are slightly larger than the Polish miniature rabbits

Lol, I've yet to eat any I have had, they make good compost for the garden
