Thank you to all for the warm welcome. I bought some durvet strikeIII is anyone familiar with this product. As it was suggested to worm them since I have never done this.
I think the two chickens I got at the feed store recently that I thought were pullets are roos. They stand off to each other and stretch their necks out and jump at each other. It also looks as if the tail feathers are starting to grow out. No crowing yet. They are about 18 to 20 weeks old.
