I have a grey cockatiel named Yellowhead who is really a racist, He hates lutino babies. He himself is grey split to pied,cinnamon,pearl and lutino and he has a permanent girlfriend (lutino), I say permanent since he is very devoted to her and absolutely wont breed with anyone else.So these two do get lutino chicks sometimes.. When he was younger he wasnt feeding the yellow ones at all,so when they fledged, I had to assist feed or they would starve; once there was one lutino baby left in the nest (his siblings fledged) daddy attempted to hill him,poor baby was bleeding all over but luckily I was able to save that one..Now he has a clutch again with 2 lutino babies in it, I found one stone cold in the corner,then another-with bite marks.. Otherwise he is a wonderful parent (to all other chicks,he doesnt mind pieds or cinnamons,just lutino is his problem) My husband sometimes jokes that Yellowhead feels that the girfriend cheated on him and yellow ones are not his,since he is grey himself. Does anyone else has this experience with racist cockatiels?
