This is a video of one of them "singing" and I can never catch who's doing it! I finally kept setting the tablet near them and happened to catch it (without any video pic). Have you ever heard this before??? It's pretty but unusual. First Chick Second Chick So I'm trying to figure out what these TSC chicks are! Any help or advice is appreciated! One of them is definitely singing but I don't know if it's natural or the result of the song birds in the area. It sounds pleasant though and I hear it ALL DAY, the same little chirpy song. My guess on the bottom one is Mille Fleur but the top chick I'm not sure because the leg feathers are different (it has long feathers on the leg and not the same shape or length as the bottom chick).
