1 problem.

3 Q. Would you accept that a chicken's beak does have nerves in
4 it?
5 A. The entire beak, yes.
6
7 MR. JUSTICE BELL: When you say the "entire beak", do you mean
8 throughout the entire -----
9 A. Yes, a bit similar to our nails. In the back of our
10 nails we can feel, but at the very tip, we do not.
11
12 Q. That is why I am asking. When you say the "entire beak"
13 are you saying that there are nerves throughout the entire
14 beak or that somewhere in the beak there are nerves?
15 A. Not throughout. They start, they have some at the back
16 and then disappear. They have some receptors but the
17 actual connection between those receptors and their ability
18 to sense or cause pain is not, as far as I know, it has not
19 been proved. This paper supports that.
20
21 MS. STEEL: Where does it support that?
22 A. You probably should have read it before. It is there.
23 It is on the first paragraph on the 19th line, it says:
24 "It is, however, not known what kind of information the
25 damaged beak conveys to the central nervous system".
26
27 MS. STEEL: That is not what you said a moment ago.
28 A. You can go back to the transcript and read it again?
29 That is what I said.

31 MS. STEEL: "They have some at the back then disappear. They
32 have some receptors but the actual connection between those
33 receptors, their ability to sense or cause pain is not, as
34 far as I know, it has not been proved"?
35 A. That is right.
36
37 Q. Right. The paper does not say anything about the receptors
38 disappearing, does it?
39 A. No, what it says is that -----
40
41 MR. JUSTICE BELL: No, it says: "It is not known what kind of
42 information the damaged beak conveys to the central nervous
43 system". If it is the same as human beings, nerves can
44 serve different purposes. You can have nerves which give
45 you a positional sense, for instance, without any sense of
46 discomfort or pain?
47 A. That is correct.
48
49 Q. Is it the same in animals?
50 A. Yes, it is -- very similar.
51
52 MS. STEEL: Would you agree with the section about the
53 formation of nueromas?
54 A. Where is -- what section?
55
56 Q. It is mentioned in the summary: "Following amputation
57 neuromas were developing by 15 days after surgery and they
58 were well formed by 20 to 30 days."
59 A. That one, I do not know.
