Is it okay to place a baby Holland Lop with an adult Holland Lop?

Answer 1

Baby bunnies are fostered out all the time.  Meaning if a mother is not feeding or taking care of her kits; the kits can be placed with a lactating doe, and she will take care of them as her own.  Bucks usually do not pay too much attention to babies.  If the bunny is already weaned it may become unsafe for these bunnies to be housed together.  As they get closer to the junior age, 6 months, the risk of injury uncreases.  And the risk of one becoming pregnant should one be a male, and one a female.
