There are few events more rewarding to bird owners than the discovery of a nest full of newly-hatched chicks. But along with the excitement of the new arrivals may come a few potential problems. Today we’ll take a look at how to avoid and handle some of the more commonly-encountered of these.
Parrots, finches and other pet birds go from helpless chick to adult-sized fledgling in record time. As you can well imagine, such rapid development must be fueled by the proper foods, and lots of them. One of the most common causes of nestling loss is poor nutrition.
Parrots are generally easier to deal with in this regard, and most of the foods needed are readily available…please be sure to write in for suggestions. Canaries and finches however, are another matter. While adults subsist largely upon seeds, the young of most require a high protein diet that is rich in insects.
Live and Canned Insects
Be sure to provide the parents with large quantities of small live crickets, waxworms, mealworms and mealworm pupae. Wild-caught insects offer nutrients unobtainable elsewhere, and were standard fare for many species when I worked at the Bronx Zoo. The Zoo Med Bug Napper is an excellent insect trap, and is well worth considering.
Canned Insects offer a very convenient means of providing breeding birds with much needed dietary variety, and are well-accepted by most finches. I am quite sure that their role in aviculture will grow in coming years.
Other Protein Rich Foods
For reasons that are not yet entirely understood, otherwise attentive parents sometimes suddenly begin to pluck their chicks’ feathers. The attacks often center on the base of the neck, and are usually instigated by the hen, but males may be guilty as well. The behavior often intensifies over time, and can leave the chicks with severe wounds and stress-related (as you can imagine!) ailments, and in some cases can result in their deaths.
Feather-plucking of chicks is most commonly seen in budgerigars, lovebirds and, to a lesser extent, cockatiels. A number of theories have been proposed to explain this odd phenomenon. Captive animals of many species often attack or even eat their young (never clean the cage of a female hamster with a new litter!), but the birds involved in feather-plucking are most often well adjusted to captivity and excellent parents in all other respects.
Some have suggested that the behavior springs from an inherited, genetic defect or a misguided re-nesting instinct, but a proven explanation is still lacking.
Discouraging Feather Plucking
Short of pulling the chicks for hand-rearing, Bitter Apple Spray is the most effective solution to the problem. When applied to the nestlings’ feathers, this product is very effective in dissuading errant parent birds. In most cases, the attacks stop and the pair goes on to successfully raise their chicks.
Recently fledged canaries and other finches sometimes fall victim to a condition known as “slipped claw”. The rear claw (the one which points backward, in the opposite direction of the other three claws) slides forward and remains in that position as the youngster attempts to perch, eventually crippling the bird.
The condition is largely confined to young birds that are kept on hard, smooth perches. You can avoid this problem by providing your fledgling finches and canaries with thin, supple perches for the first few months of their lives. Cotton Cable and Rope Perches are ideal.
