Everything is in a rack which allows me to keep them in a secure setting allowing me to limit stress which to me is essential for breeders.

Do I have favorites? Yes the first pied I ever produced almost 10 years ago, an Albino Pied that was my first DH recessive project that took me 9 years to see through, and a Black Pastel Pied (a gift from a friend)

Even when I retire from breeding in 10 to 15 years the animals that I will keep as pet will still be in a rack system, the only animals I keep in glass enclosure are animals that actually make good display animals and they are kept in a bioactive setup, those are definitely not BP.
