The winter following the destruction of the windmill is bitter. What are three specific ways the animal suffer during the harsh winter?
You can find the answer to this in Chapter VI and Chapter VII. In Chapter VI, we learn that the winter is going to be hard because not enough food has been planted. Then at the end of the chapter the windmill blows down in a storm.
After the windmill falls, the animals need to build it again, this time better. They have to work really hard getting all the extra stone for the thicker walls. It's really hard to work when they are cold and hungry.
In January, the corn ration gets cut in half. The animals are supposed to get more potatoes, but the potatoes have frozen and are therefore spoiled. So now the animals have very little to eat.
After that, there are a bunch of executions that follow the hens' refusal to give their eggs to be sold.
So, I guess three specific things would be the lack of food, the extra work and the executions?
In the novel "Animal Farm" by George Orwell the animals have worked hard through the summer but the crops have not been as good as they had expected. The weather was very harsh in the winter. Sleet and snow came and harsh frosts. The animals kept trying to rebuild the windmill. Some of the other problems in the winter were: 1) Progress on the windmill was slow due to the terrible weather. The animals began to lose their spirit and moral became bad. 2) By January there was a food shortage. There was not enough corn. 3) The potatoes began to rot and the animals were starving. 4) The hens had to give up their eggs. They had hoped for off spring. 5) The animals began mumbling of a rebellion.
