Bunny poo is a great soil conditioner and a decent fertilizer that can be used fresh but isn't particularly great for flowering as it's NPK ratio is better for general growing and pot wants more K with less N in flower.
Fresh, undiluted rabbit manure is a 1.10-1.50-.47 fertilizer so if you have something with more K like guano to add when flowering it should be OK. I don't like the idea of using bat or seabird guano for growing as the people that collect it don't much care about the damage they do to those animals. Ignorant bat guano harvesters have contributed greatly to the spread of white nose fungus and are wiping out bat populations.
I'm not much into organics so don't know a lot about the different sources of particular nutrients tho I'm sure that info can be found here or out in the web elsewhere easy enough.
Good luck!
