[Skyblock] Disappearing Animals

IGN: LouiseXminerX
Server: Skyblock 2, On my island
Description Of Bug: Apparently animals on my island are disappearing, and half of them are disappearing in front of my eyes. So when I was throwing some eggs at a bunch of adult chickens in my egg farm, when some baby chickens spawned, they disappeared, just like that.
This also happened to my sheep, but I didn't see them disappear, they disappeared when the adult chickens disappeared as well. My sheep farm used to be filled with sheep with many colours, then they all disappeared. and when I tried to breed all the sheep again the SECOND time, they disappeared as well. Most of my mooshrooms has also disappeared.
This amount of sheep, chickens and mooshrooms disappearing is getting worst. EVEN while typing this report, one of my green sheep disappeared.
Please anyone with any advice to help me with this problem. And I'm 100% sure no one is killing them because they are disappearing in front of my eyes, most of them. Plus there are only 2 people who are added to my island and they don't go on this server any more.
Thank you in advance.
If you need the position of my island, just ask below then I'll tell you.
Note: If you need a video for proof, I can upload one unless this information is enough proof.

I should take this question but no. They are not dissapearing They are Invicible. If you shoot them with an arrow they will get hut. This is also a well known glitch that happened to my pigs too they Dissapeared and i shooted arrows everywere and i heared an Oink but no pigs arround me. This is a Minecraft glitch.

 

Um... are you saying they get splashed with a invisible potion?

 

No its a glitch they are invisible because they glitch. It happened to me also in singleplayer

 

Well I can't hear a single sheep say anything since you said that when your pig was invisible you can hear them snort.
Plus I was punching everywhere and I didn't hit a single 'invisible' sheep.
Plus I can make a video on youtube and show you how they are disappearing in front of my eyes.

 

Have you tried:

• Deleting your Minecraft client and re-installing?
• Other Minecraft versions?

 

I ment if you shoot them an arrow I can hear My pigs oinking

 

That might be the problem I guess :o Thanks ^-^
I guess I'll just kill most of the animals in my farm since I have heaps.
Thanks @ItsHarry and the people above for helping out :D
