Parrots through Nether portal making Realm crash

Hello,

Yesterday, me and my friend were playing on another friend's server. I was in a jungle, and I just tamed two parrots. They were both on my shoulders, and I wanted to put them in the portal with me so I can bring them back home. I first went in the portal with both of them on my shoulders, but it didn't work, so I went back off my portal, removed the parrots from my shoulders, and I tried to enter the portal hoping they will teleport to me in the Nether. WELL. At the exact same moment where I was supposed to be teleported to the Nether, me and my friend got kicked, and we were unable to connect to the realm (Error message saying we didn't got an invite to play on this Realm). So I called my friend who owns the Realm and asked him if he could reinvite us to the Realm. Well, he was also unable to connect to his own Realm. He has to put a world backup to make us able to join the Realm again.
In case if you need to check Realm log, here is the Xbox Username of the server owner: shadzap

Thanks a lot, have a good day
