I was offered to adopt a green cheek and american dilute this week. The breeder sold parents and is not raising birds anymore. She took them away from parents 3 days ago at 6 wks. I have been trying to handfeed but they are fighting me. I have been getting 4 to 5 cc in them each feeding. They do not act hungry no head bobbing no sounds. They look healthy but not eating well. Can they survive at 6 wks without formula and will they start to eat other foods. Any help would be appreciated.
