Adding the possibility of multiple "other - please specify" responses to a single survey question

Hello,

I was hoping to get some advice about how to create multiple "other - please specify" text boxes in a survey I’m building. I searched in Qualtrics and here in the community but could not find any specific tips. For context, the survey question is the following:

Which of the following vertebrate animals have you used for your own research during the past 5 years? (choose all that apply)
Mice
Rats
Other rodents
Cats
Dogs
Pigs
Cattle, sheep, and/or other livestock other than pigs
Ferrets or other weasels
Non-human primates
Opossum and/or other marsupials
Rabbits
Amphibians
Fish
Reptiles
Other – please specify one animal per box

What I tried to do was use display logic to add a new “other” with a text box to appear if the first (visible) “other” was checked. (In fact, I added 5 “other” fields this way.) However, it wouldn’t actually work the way I intended because the new “other” options wouldn’t appear, and it generated a warning in the survey. The reason I want to have multiple text boxes is that the responses get piped to later questions. I hope this makes sense!

Thanks for any help you can provide!
