Well we didn't think they would start breeding so quickly, Hubby only built the aviary 3/4 mnths ago, got some birds... next thing you know we had a couple of babies......one poor little bub, we took to the Vet his little legs were just straight , the Vet said his legs were fused ... so the best to do was put him to sleep... poor little thing, now we have one his aren't to bad , hopefully they will get better. I didn't think that they would breed that quickly......We weren't really worried if they did our not. looks like they are trying again....so if anyone has a suggestion on a good book .. I would be most appreciative....
