Flabby rabbit

[Tristen23]

I was given a rabbit that is very boney and flabby. His skin is not tight on his body, I can easily grab and stretch it.
He has an excellent appetite and seems to be very bright. Sometimes, his poop is very small, black and clumped together.
What can I do to fatten him up? Is there anything wrong with him?

Is he skinny,like bones showing ? And how much are you feeding him ?

And how old is he? It's normal for young rabbits to have loose skins, the rabbit "grows into his skin" a bit before he reaches full size.

Those little clumps of darkish poop could be cecals...do they kind of look like a bunch of little grapes covered in mucus? If so, that's pretty normal. Rabbits usually eat these as they have lots of beneficial bacteria for their digestive system.
Considering he's got a good appetite (he's drinking well, too?) and seems to be "bright," for the moment I'd rule out anything serious. Keep a close eye on him though. If he stops drinking or goes off feed you may have an issue.
Anywho, you may have just gotten a skinny rabbit. I'd worm him just to be on the safe side (I use Wazine, lots of good info on dosage info online, I can't remember off the top of my head what it is), but that's just me.
If you haven't already, add good quality grass hay to his diet. The fiber is great for the rabbits and help keep the GI tract moving well. You could add a little bit of a mix of barley, oats, and BOSS either on top of feed or if he digs it out on a little board in his cage or something like that. Don't feed a lot though, roughly a teaspoon (less if he's a smaller rabbit). Once he's eating and drinking regularly he should start to gain weight.
Good luck! Keep us updated

He is showing bones and I am currently free feeding him and just turned a year old in January according to his pedigree. His poop did remind me exactly of grapes.
The whole herd was wormed about a month ago and they all have a little hay a few times per week. He seems fine to me in every other way, I'll try supplementing his diet with oats and BOSS. Thanks.
