Hi fellow Washingtonians, sorry for the intrusion, but I am wanting to see if any of you would be willing to help us replace a chicken that we just lost to a coyote attack. We have a small backyard flock of 4, and my 10 yo daughter would like an Easter Egger pullet as a replacement for Squirrel, the Welsummer she named that was killed

. She was actively engaged in taking care of the chickens, so she is quite sad about losing Squirrel. It was a daytime attack in the middle of suburbia and I was literally 50-75 yards away around the corner of the yard! I saw Chickmunk, the other Welsummer, running towards me with an alarm call, ran up and saw a coyote running down the driveway. They have a secure coop and run, but I was in the yard, so they were free-ranging, but were just out of my direct line of sight. I guess we won't make that mistake again!
Our other 4 chickens are 20 weeks old so we would like a pullet the same age range so integration might be easier. We also have a budget of $20, but would be willing to drive up to 2 hours from the Seattle area if we need to. I checked Craigslist, and most of them offer chicks, and we don't want to raise a single chick as it might get lonely while growing up.
Any suggestions, or chicken lover you can point me to would be most appreciated! Thank you in advance!
