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!
