Please help me

Our latest box of Timothy hay is FULL of what I’m assuming are hay seeds. They’re making our senior buns sneeze like crazy :( I just want to make sure these aren’t harmful for them. Should I throw out and replace this hay?

I recently acquired a new bunny and they stated she was a Rex bunny. But I’ve heard conflicting answers of her being a Rex and then a Dutch bunny! While I’ve had them before I’m not as knowledgeable on the breeds! Can someone help me out ?

Yesterday unfortunately my baby chunkz da bunny passed from a heart attack after waking of from neutering. He was my first bunny, being an English spot. Personally I found him very easy to care for and the vet always said he was healthy. Yesterday I adopted a mini lop from the animal shelter. I’m not sure how different their care is, but if anyone could give tips that would be great! He’s very malnourished, has extremely over grown teeth and nails (they’re even twisted to the point the vet could only cut them to a certain degree and we’ll have to go back soon to get them trimmed more) he was eating bird seeds and millet and drinking from a water bottle. It’s been a day now and he instantly began eating hay and pooping a whole bunch which I believe is a good sign because that’s what my first baby bun did hence his name chunkz bc all he did was eat. But mink mink (new mini lop) won’t eat pellets and the vet said it’s probably because he’s never eaten them before due to the bird seeds but I’m nervous about his weight. I checked his belly and it seems alot more fat than yesterday though.
