Welcome to BB Haythere (haha)! There’s a new Welcome thread BB is starting where February newcomers can post to get their name out there: https://binkybunny.com/FORUM/tabid/54/aft/165121/Default.aspx . Feel free to post and introduce yourself more formally (or just your rabbits) there as well!
Fear while cooking is not uncommon, and there have been posts in the past about it (Search function is down, but if you google “site: binkybunny.com ________”, you’ll be able to search). Here’s one: https://binkybunny.com/FORUM/tabid/54/aft/157455/Default.aspx (just don’t reply to old topics; make a new one like you’ve had!)
It’s important to narrow down if it’s the sound of the oven or smell of the oven that’s setting them off. If you live with someone else, I suggest an experiment where someone starts up the oven, opens it, etc.. (without cooking anything), and another person be with the rabbits, and see exactly what/when the fear takes place. If it’s noise related, maybe playing music by the rabbit’s room when you’re about to cook may help drown out the sound. If it’s the smell of cooking food in the oven, closing the door or burning a safe candle may be best. Maybe you could time your cooking time with their feeding time, so they get a positive association? Another maneuver, though its effectiveness varies depending on what the rabbit is thinking, is having the rabbits in view of the oven so they can see what it is and that it’s not some mysterious predator. When Wick shows fear to something, like the food processor, the stick-sound of a lint roller, I carry him to it or let him sniff at it so he establishes it’s A-okay. … Always be cautious of hot ovens and rabbits though…
