Yes, they may peck at glass. I would go over the area again juest to make sure you got it all. I live on an old farm where people have thrown away old broken bottles and dishes for 110 years, and I have to collect small pieces of glass near my coop in a coffee can. Every year more works up to the surface.
THIS! So much of this on Mars. I till the dirt and actively look for shards and bits, but it is always coming to the surface after a heavy rain - like little diamonds strewn out across the field. I've been repeatedly going over the areas where I want my girls to range so that in the spring when it is ready it will be at least sorta-safer-kinda-maybe-I-Hope.
I worry so much about their feet uncovering something I missed or that migrated upwards through the soil.
