Why would you be afraid of coyotes? They are just scavengers, mostly afraid of their own shadows.
And deer pay them little attention. Where I live, I get to observe lots of wildlife in their natural behavior.
Many times I've watched deer and coyotes mingle and interact. Deer will continue feeding and not even pay attention to the coyotes.
Now, it's a whole different game if a bobcat comes around. The deer (especially a momma doe) will go crazy if a bobcat is nearby.
