As I understood it the stress thing is not about individual symptoms on a specific day, but rather about two things: (1) Whether an exposed hen gets disease at all. That is just like us getting flu when we are run down. And (2) Virus shedding which impacts how they infect other chickens.
I appreciate the chat.
Well, she's definitely not experiencing stress and nor are Mary et al. But her case is so advanced I assume she's shedding.
Wow. Once again I conclude Australia is miles ahead in poultry care.
It's not just Australia that is miles ahead in poultry care, many other countries including the UK have made major progress in chicken knowledge, particularly regarding behaviour studies and welfare. Other creature welfare has never been big in the USA. It's got a lot to do with culture rather than the means to do the research in my opinion.
Collaborative research centre. When researchers with the right mix of knowledges, capabilities and equipment work together on problems that merit public funding, regardless of which uni they're based at. Sometimes industry advises/participates but all the work and vision is under the leadership of the researchers. CRCs are usually seeded with 8 figure sums, do their work, publish, and wrap up when the goals are met.
Thing is, I'm not convinced I can buy chicks that have been properly vaccinated. The vaccine has to be kept in liquid nitrogen for viability and it comes in batches of 1000 doses. I can't see chick hatching people doing it right, even if they say they are.
Experiment 3 of project 1.5.6 is a good starter for anyone who's not accustomed to reading research.
