Hi, This year about may 5th I got some Nankins, I was very excited because I was waiting for them for about 5 months. As chicks I put them in with 3 of my older Mille Fleurs and they where doing great, but as they got older around their back area was just pin feathers. I thought that was quite strange and then I talked to the nankin breeder and she had the exact same problem, and so did another lady. They are approximately 3 months now and I separated the about 4 weeks ago and their tail feathers are growing in quite slowly, and I was wondering if there is anyway possible to speed up this process as these are show birds and missing tail feathers don't look to great. Thanks.
