My chickens have also shown no interest in rolly polly/pill bugs. (I think the bugs prefer dead plants to live, but seem willing to branch out.)
However, my girls initially showed no interest in dandelions either, until the new girl decided she likes the greens. I've noticed that if I can get the new girl to eat something, the top hen gets jealous and steals it from her . . . I am slowly training them to eat dandelions this way. Perhaps pill bugs could work the same way.
Hey guys I bought a couple Rhode Island reds a few months ago and at first they didnt really eat any bugs not even worms. They wouldn't even eat their pellets i had to buy smaller crumble. They did eat raspberries,blueberries,and grapes but that was it.
So I gave them a strip of bacon one morning and they went nuts chasing each other around for it i was laughing so hard I almost peed myself. Later I gave them a piece of pastrami and a slice of cheese which they also fought over. One day I let them into my garden and heard a commotion only to find that Tina my bigger Lead hen had found a colorful grasshopper and Margaret the faster hen was trying to steal it away which made her run and gobble it up. Since then I realized they would eat grasshoppers so every other day I go into the farmers field next door with his permission and I catch grasshoppers by hand and but them in a 2 liter bottle with holes. Easiest way is to walk slowly making them hop and then watch where they land and cup your hands over them, they are so dumb they will jump right into your hands trying to escape,Just before dusk is best as crickets will emerge everywhere too by the hundreds and chickens love crickets the most . I hear your supposed to cook them first because of parasites but meh I give them Diatomaceous Earth and apple cider vinegar in their water to kill parasites anyway.
I later found some real wriggly active worms and when margaret saw them move she couldn't resist but to eat them and when tina saw margaret eat about 6 of them she finally said screw it imma eat them too and did. Since then I have given them slugs and spiders big creepy ones and centipedes millipedes pincher bugs you name it them creepier and faster it moves the more they want to eat it. Maybe pill bugs are to slow I thought? It seemed that they When we play our favorite game of walking around the yard lifting rocks and logs up the chickens pounced on everything underneath completely ignoring the pill bugs. That is until yesterday, I was lifting rocks up for Tina when she grabbed a long creepy centipede and when Margaret came running over to see what she had Tina gobbled it up quickly and looked down at all the dispersing pill bugs like oh ya I already got the goody haha, But just then whether out of spite or hunger Margaret pounced on the scattering pill bugs and started gobbling them up, Tina who had always ignored the pill bugs watched Margaret gobble up about 8 or 10 before finally realizing and it was so funny to see It was like she was like *** you can eat those fuking things! And BOOM they both started annihilating my pill bug problem. I went around my yard lifting rock after rock along my stone wall and my girls pounced on not just the crickets and spiders although the go for the faster stuff first but also gobbling up any pill bug in sight. So I think if you can train one chicken or duck whatever to eat pillbugs (roly poly bugs) Then I believe once the others see they will eat them too, chickens are weird like that they want what the other one has.
A trick I use when I introduce new foods is to only give one piece so they have to fight over it and want it more, once they want it once that's all folks! Well good luck I hope this helps with your pill bug infestation I know mine is about to become extinct.Also they feed on dead underbrush and leaves so you can rake it away and make sure you have no wet/damp piles of anything on the ground, put in up on pallets as pill bugs love moist dark tight places. Or just buy more chickens if one eats them they all will, I think another type of chicken really likes to eat them too you could research which types of birds eat pill bugs religiously and buy a couple of those problem solved. Ok gtg feed the hens goodluck, be creative, experiment and research online for ways to improve your coop find free foods for them build maggot dispenser cricket farm, dust bath boxes with D.E. Nesting boxes etc.
