Are these weeds safe for piggies?

Hi

I've got some little weeds growing in the lawn and I've been pulling them out before putting the boys on the grass but it would be helpful to know if they're safe so I potentially don't have to. They're hoary willowherb (pic 1) and radium plant (pic 2) according to PlantNet. I can't work out what pic 3 is.

If anyone knows that would be great

The third pic looks a bit like a foxglove that’s gone to seed? If it is then don’t let the piggies feed on it as foxgloves are poisonous to animals and humans in general as they contain a chemical that can cause irregular heartbeats. Although I can’t imagine it would be sticking up above the grass if it’s in a lawn? Perhaps not, they tend to go very woody after they have flowered.
Could it be an orchid?
I don’t know if the other two are safe for them?

Its very small so I doubt it's a foxglove so an orchid seems more likely
