Yes, that is exactly what I thought as well. When the breeder sold the chicks to me she said that one "might be" a Bielefelder but she did not say hybrid. Still, I am fine because the chicks are healthy, I am not a breeder (yet...... I am reading and being tempted), and I was looking for sweet natured chicks for my already sweet natured flock. The top chick is worrying me. Though I live on acreage, the builder of our neighbor's home put their house as close to ours as legally possible, mere feet away. The neighbors are very elderly (Korean War Vet) and in very very poor health. I can't have a rooster being noisy because of this. And I can't kill a chicken or give it away knowing it will be killed. Hopefully the top chick is just what an Ameraucana/Cream Legbar hen looks like at 2 1/2 weeks. There are not many photos to help me know. One thing about chickens that has surprised me... I am loving raising and stewarding these animals way more than I expected.
Yeah...I'd be keeping a close eye on that top one if I were you. It's looking rather "boyish" to me. And I know what you mean about discovering "chicken love". I have over 80 chickens now because I love them so much.
