This evening I sat outside for a bit with my chickens and gave them some mealworms and watched them and petted my tame one. I THINK there were ticks falling out of the maple branches overhead and onto my self! I found like 5 ticks on my clothes and tried to get the chickens to eat them. They'd maybe peck at them but that was it. One got flung back onto my shirt as my hen tried to get rid of it. What gives? I thought they ate ticks?
