How to tell how old The Baby Rabbit is?
If you are caring for baby rabbits, whether you found them abandoned, have a pet that gave birth, or adopted them, determining their age is the first step to figuring out exactly what care they need. It is even complicated for experts to define a rabbit’s exact age without examining the bones and eye lenses post-mortem. Still, with a few physical and behavioral clues, you can get a rough estimate of your baby rabbit’s age.
Check if the baby rabbit’s eyes are open. Baby rabbits open their eyes at approximately ten days; this is also the age where they become more adventurous than before. When your baby rabbit’s eyes are open and moving in a short, tentative walk, it most likely is between 10 to 14 days old. At this age, the rabbits’ ears perk up, hairless at birth, and develop a full coat.
After around two weeks, mostly baby rabbits are opening up their eyes, ears, and gaining fur. They are growing up and need a little extra care, especially for their eyes and diet.
Weigh the baby rabbit. Newborn baby rabbits can weigh between 1 to 1.4 ounces. At between 15 and 20 days old, they can weigh between 3 to 5 ounces when they venture out of the nest.
View the fur of baby rabbits. A newborn kitten will have little to no hair on the body. A baby rabbit will have a complete coat around 14 days old.
Check the baby rabbit’s ears. A baby rabbit’s ears are closed between 1 to 7 days old. Between the age of 9 to 14 days, the ears of the baby become erect.
Note the baby rabbit’s reaction to loud noises. If a baby rabbit is nervous and jumpy in response to sudden noises, it is at least 21 days old.
