Rabbits die easily in cloudy and rainy days

Hello, everyone. I have been raising rabbits for almost a year. Since the beginning, rabbits are easy to die on cloudy and rainy days. Ask the heroes for advice-how big is the rabbit? -- I'm glad someone asked. I originally wanted to be hopeless. I'm from Zaoyang, Hubei Province. Since I just started raising meat rabbits on December 5 last year, I stumbled until now, when it comes to rainy days, that is, 40-60 days, it's always easy to die. By the way, I'm indoor farming, it's a school. The metal cage is used and the back-to-back style is used. Pay attention to the prevention of coccidiosis and recommend the use of microecological agents to control digestive tract diseases! For reference only! -- have coccidiosis been prevented? in this case, coccidia are more likely-- hehe, pay attention to coccidiosis prevention.
