They're probably not mixed unless they have red sexlinks.Hi All, been a while. Anyhow, I ordered from Sandhill, first time, and got my letter and chicks accordingly. June 26. 10 Blk Java, 10 Mottled Java and 5 Delaware. Plus 9 "filler". All went well, though one Java passed in hours. I didn't expect that and wasn't hovering over them. We feather sexed them just for fun. Anyhow about those 9 "filler" chicks? I have no idea what they are. I can't post pics as I can't seem to figure out how to move them from my phone to this lap top. Does anyone know. Would they be a breed or mixed? I've emailed today so I expect it to be a while before I hear back. I will say I had called about my order, and they texted me back and then called with a heads up. I was concerned with the heat here in NYS. I'm already planning next year's order since they're out of what I want. So, does anyone have any idea what these 9 fillers might be? A breed or mixed? They're golden and pretty. We feather sexed them to be all girls. lol but I don't think I can keep them.
