They need to eat the grass off of grass blocks if I remember correctly EDIT: It is apparently a bug with the plugins on the skyblock server. I don't have a sheep farm so I had no idea...
I have the same problem with my sheep it must be a bug because my sheep have tons of grass to eat and nothing has happened in the past 2days
No, they are definitely eating the grass - I can hear them and see the blocks eaten. Also, they were doing fine before the upgrade. 6 of them were dyed but I did have a couple normal 'white' sheep so that's not the problem either.
If you get a certain number of sheep, a Spawner won't spawn anymore. Same goes for the sheared sheep.
I've had the same amount of sheep since before the update. I think after 1.6 upgrade, they stop growing wool back.
Ya I joined right before the update and got sheep the day of the update... so I don't really know but it is pissing me off so if anyone finds an update fixing it to come out soon please respond.
