please can you tell me how old your royal is as young royals can be fussy eaters pls try rfuk as there are more experienced this site is good but a reptile forum is best advice i can give , factors include weather and season time , ive heard off ppl driving it around hope it eats pls tell me weight ect, i was saying maybe go out and buy a gerbil but again as ive said once they eat gerbils there hard to turn them to rats or mice but try the chick and i dont think really you want to cull a gerbil id stick with a chick , please dont think im cruel
