I have just got my copy...... Had a quick look through and now I am almost scared to open it again.....I didn't realise that chickens got so many illnesses!
I am very impressed.
There is a bit about each disease, what it looks like and how to treat it. There are some very useful sections in the middle for you to determine what sort of illness your chicken might have. These sections are divided into, for example,Diseases Causing Sores in the Mouth; Diseases Causing Breathing Difficulties; Diseases involving movement etc..etc.. so that if you get the six or so diseases which involve movement you can look to see which it is that your chicken has and if possible get treatment quickly.
There is a section involving post mortems at the back which is just too scary at the moment, but I will get to it.
It's definitely one for the bookshelf, there if you need it but hopefully you won't.
