if it was a young mother that common. they will figure it out. feed them as much as they want. rabbits are great food resource. my grandfather had 300 at one time when I was growing up. great memories standing on a bucket skinning them with him. ill thank OP for bringing those memories back up.
try this! season and grill the rabbit pieces to brown good. then put them in a crock pot with tad bit of chicken broth. cook till falling off bone. remove the bones and shread it. place meat back in crock pot and add some bbq sauce. cook while longer on low. man that's the best bbq sandwiches on earth I think. lol
the livers are top shelf also. very mild flavor. careful with them though you need steady hand to cut that gull off without puncturing. if you do that bile will ruin it.
enjoy the rewards of raising rabbits!
