Chronic egg laying is a maladaptive, behavioural disorder commonly seen in pet birds which repeatedly lay clutches of infertile eggs in the absence of a mate. It is particularly common in cockatiels, budgerigars, lovebirds, macaws and amazon parrots.[1] Birds exhibiting chronic egg laying behavior will frequently lay eggs one after the other without stopping to brood them once the typical clutch size for their particular species has been reached.[2] Excessive egg laying places a strain on the hen's body, depleting resources such as calcium, protein and vitamins from her body and may lead to conditions such as egg binding, osteoporosis, seizures, prolapse of the oviduct, or peritonitis – which may lead to her death.[3][2]
