One more question from a newbie. I have 3 jumbo japanese quails. I think they also call them coturnix. They are the regular brownish color. Out of the 23 hatches I've had I have gotten 6 yellow ones. The oldest one (2 weeks) is growing white feathers. All of these yellow ones have a little black spot on the top of their head, and some of them have a tiny black spot on their back. Here is a pic of one of their heads. A local here (I live in Yucatan, Mexico) told me it was a genetic defect, and it's a bad thing. I've read online that this has happened to others and they have died in the first weeks. When I noticed the brown chicks curiosity about the yellow chicks ear holes and black spot d I trimmed their beaks and left the yellow chicks intact for self defense. They seem to be getting along just fine. I've also read online of other varieties that look like this. A&M or Texan? Can anyone identify these? Have you had ones like these hatch from the brown variety and grow to full healthy size? Just wondering... Thanks so much!
