Pippi and Rusty were both neutered around two years ago, and both started humping each other this time last year. I put it down to the days getting longer and brighter, signalling their brains that its springtime aka lets-make-kits-time to a bunny.
Pipp and Gina have both recently had the odd amorous moment recently, which I’m putting down to spring. Both started before we got Podge, so its not the new bunny that caused it.
Pippi also got amorous with both girls during the first of yesterdays long quartet bonding sessions, which triggered off a brief hair fog
If Diggy is having bonding sessions with another doe, she will come back smelling quite different. If you are planning up bonding them as a trio, it might be worth trying them as a trio during the bonding sessions? I tried bonding my two girls, so they could end up a trio, but the hair flew when I bought Pippi into the mix, as Jenny just would not share him. I ended up getting a second boy, bonding him with Gina, and am now working on bonding them as a foursome, which is going way better than trying to bond the three!
