This is my English GCSE essay could anyone be kind enough to give me an estimated grade?

No need to get in to a flap!
Many of you may have seen Hugh Fearnley Whittingstall's program on the television, Hugh's chicken run. He has shown how a ‘standard' chicken is treated and the benefits of changing to free-range chicken because of the ethical and moral issues. The main phrase Hugh uses in this program is ‘Free-range is fairer' but is it? The main flaw with this theory is the assumption that animals such as chickens experience (or even have any) pain and emotions like human beings, so therefore are you not saying that chickens have the same brain and intelligence as a human? You cannot make a statement about something you are unsure of, such as saying that chickens prefer to run around in the out doors, pecking away at the ground having to find food with no assistance. Nobody has ever been a chicken, am I not correct? So how could you know what a chicken wants? For all you could know chickens don't like to move around and prefer the enclosed area where food and water are provided for them, logically surely this must be easier for the chickens. Although the chickens are packed 17 chickens per square meter, just because it would be uncomfortable for humans to be in those conditions doesn't justify that chickens are not content living like that. As quoted from Ivan Pavlov ‘animals do not feel and have emotions such as humans, they do not think whether they should be where they are, they do not fear anything or know anything.' The main purpose for the chickens is to keep the human race surviving, as do all animals, it is not the other way around. The chickens are going to die the same way and end up in the same place in spite of whether they are free-range or standard. Many people who are in favor of free-range chickens believe that it is a better life for them because they get to be let out but to every painting there is a crack. The fact of letting the chickens out is not mandatory but optional, and many statistics say that the majority of birds decide to stay inside. The chicken's world population is approximately 19.5 billion! It is increasing by 3.5% every year, but how do we control it? Free-range farms house not enough chickens for the large amount of area it has but on the other hand an intensive chicken farm has a high chicken density per square meter and in consequence will help to meet the every day UK meat habit which is about 128,000 broiler chicken each day. Many people don't have free-range chickens either because they don't care or they care afford it. The prices of free-range chickens are simply ridiculous! We are in the midst of a recession and the only extra you are paying for is the way the chickens were treated and for that you are paying an extra £4-£10 which in my opinion is shocking. Many people who have eaten free-range chickens say you are paying for the extra taste but that ‘excuse' is not liable reason being that even if free-range does taste better there is something amazing that was invented called spices! Salt, pepper, and rosemary all these spices make chicken taste better. Just for the ‘fairness' of chickens, you are singling out the people who can't afford it and putting pressure on them to commit a task that they simply can't perform. We are living in a world where the human population is growing rapidly, thus we need all the space available for living. If all the space is taken up by fields of free-range farms then in theory you are placing the so-called rights of chickens above humans, does that seem right to you? If we replace the free-range farms with a couple intensive chicken farms then not only will we increase the amount of chicken produced each day we would also reduce the amount of space occupied leaving much more free space for construction of flats for humans. So intensive chicken farming is an economically better way for the future.
When free-range chickens are released to have a run about they are expected to get their own food. Because chickens lack the intelligence to know what is bad food and good food they will eat anything they peck up from the dirty ground. Furthermore the chance of the chickens picking up a disease and passing it on to the rest of the chickens is very likely while there is hardly any chance of an intensive chicken to pick up a disease because they eat and drink the food and water given to them which is of course 100% clean and safe. So they don't have to even move a wing! To be honest the truth is, although many of you still believe - even after reading my article - that chickens are treated badly in intensive chicken farms, you can't make that assumption. Not only is it inaccurate but untrue. Yes I do agree to a certain extent that chickens are treated unfair and deserve better treatment but intensive chicken farms are used mainly for the benefit of human beings and with out them it is undeniable that the country let alone the world would gets its daily chicken habit! Personally free-range farming is too inefficient, expensive and slow to be the main supplier of Britain's chicken. After you have read this article what do you think about free-range and standard chickens? Do you really think free-range is fairer?
