Any cockatiel breeders out there that can help me? I have 2 pairs of cockatiels that I`ve been trying to breed for 3 years!My problem is that they constantly lay infertile eggs.It`s not just one or two eggs being infertile....It`s the whole clutch! I feed them a seed based diet but I supplement it with egg food and leaves a few times a week.I also started giving them a vitamin supplement in their water.A cuttle bone is also in there.I feed them various fruits but they don`t seem to touch it.I tried giving pellets but no good results. Could you reccomend a fertility supplement? Am I doing anything wrong? I really want to get babies from them before they get too old. This is driving me crazy!One pair did give me one baby about 4 years ago but I gave him to one of my friends.So I know their not infertile. They laid one clutch each this season but infertile again.Any suggestions?
