Being a first time chicken raiser I thought I needed to worry about dogs, cats, hawks, coon, possums, etc... but this was unexpected. I decided to put my two 3 week old chicks out in the back yard for their first adventure in the grass. The idea was that I just wanted to see how they would react and then bring them right back in. Not 2 seconds after I put them in the grass did a large robin swoop down and start attacking them. One (the unfriendly chick) raced between my feet and looked up at me as if asking for me to pick her up. She never does that. She usually flaps her wings and protests when I come near her. The other chick bolted under the deck steps and waited for me to come get her. I had no idea I needed to be worried about robins.
