Checked it out today Adam, sorry to hear gritter's are getting your fruit that sucks, well hang in there during these trying times and stay safe.
It would be hard to feed the rodents any special treats as the chickens would probably get it too... Guess traps or the feral cat thread would be about your only option, if they are nice to your chickens.
Sorry to hear you were afraid to get fertilizer per in the video. This may help with your future purchase if you know a truer risk of Mortality. Any & All can get infected = Infection rate but the Mortality rate is significantly less for your age group with 70 & above having a much higher Mortality rate. If less than 9 I believe it was still 0 percent Mortality rate when this was printed... All may get the virus & be infected, but Mortality rate is great if less than 30 yrs of age and no disease,no low immune system, etc.
Also total cases = denominator. So far this is only confirmed cases & it should greatly increase as we find a much larger percentage of the population is currently infected with a large number asymptomatic. This should cause these mortality percentage numbers to decrease in the age groups.
