Congrats on your rescue - most of my chickens are also rescues. Several came from Animal Control when they had to seize them from a Vietnamese family who didn't understand city law. The immigrant family had 18 chickens in their apartment. County law allowed 4, but not necessarily IN the apartment.
Last week I was leaving the grocery when I heard 2 of the cart-fetching kids talking about the chicken in the parking lot. (My ears perked up.) It seems there had been a chicken out there for a week. The clerks were very concerned because this hen kept darting in between the cars and they were afraid she'd get run over. Several people had chased her but couldn't catch her. No one knew anything about chickens.
I asked the store manager if she'd like me to get the chicken, and she said yes. So I went home, got a cage and net, and waited until the hen roosted in a pine for the night. It wasn't a big deal but still drew a little crowd because none of the onlookers have chickens. The new hen is probably an Aracauna cross. She's was kept separate from the other girls, wormed and checked over closely. She got her freedom in the aviary a couple of days ago and is doing fine. She's very confident and even the roo won't mess with her. What should I name her?
