What is one of the problems the animals encounter as they begin to discuss the coming rebellion?

The animals had to prepare for the rebellion by learning to read and write, and this activity “fell to the pigs, who were generally recognized as being the cleverest.” The pigs also had to counteract "lies" told by Moses the rave, that talked about a better place beyond the farm. The animals also had to overcome their worries that they would not have food to eat if Mr. Jones were no longer in charge. Molly in particular is worried about not having sugar. When the rebellion itself occurs, the animals have no problem scaring Mr. and Mrs. Jones away from the farm.
