Ive had two fischer's lovebird since 2017 October when they were roughly 1 year old. The pair was picked out from the overcrowded little cage and i brought them home. Reading up online, i assumed thay although it may take time - ill bond with them eventually. Their reaction to everything in that period was the same as a wild bird being put in a cage although its spacious. Months passed and it turned into an year with no progress and they've showed a nervous and frightened behaviour all along. This led to me assuming that they were probably mishandled at the breeder's but there was still hope. Due to fans in the house , ive been unable to let them out of the cage but i finally took a bold step and shifted the cage to the covered balcony -where one of them enjoys retreating in a corner and chirping and the other being fearful and not leaving its cage. Despite of my efforts , they've been constantly afraid of my hands and presence in general-Its to the point that im beginning to assume they'd rather starve than eat from my hands. After giving up a few months back , my hopes relightened and Ive been spending almost 2 hours for 2 weeks trying to bond with them in that hot and humid balcony which leaves me all sweaty but im beginnng to give up again. Sadly theres no treats to lure them or toys to play because they show disinterest it almost everything i do and i feel like theres no way to tame these birds. Theres no video on youtube that provided helpful and i generally feel lost regarding taming and im unsure of what i might me doing wrong. It feels like everytime theres a small spark of trust , it goes the otherway and they begin to hate me more. I need help
