A very ballsy fox came into my yard today and took a hen.
I was outside with them! I put all the chickens back into their lot so I could "deal" with the issues at hand. Unfortunately the hen didn't survive.
The other chickens have been uncharacteristically clucking and carrying on all afternoon. Do they realize something has happened? Can chickens mourn the loss of a flock mate?
Also what can be done to deter other predators from coming into the yard? Should i commission my husband to just start "marking his territory" all over our property?
