396  Hand-Rearing Birds

              electrolyte solution (such as Pedialyte ) or lactated Ringer’s solution (LRS) very carefully on the tip
            of the bill and allow it to roll down the bill for the chick to swallow. If needed, gently open the
            mouth slightly and insert a drop in the side of the bill. Be careful so that the chick does not aspirate.
            Repeat this a few times. Follow the drops of electrolyte solution with drops of 50% dextrose if the
            chick is still poorly responsive. If the chick is extremely young or has been chilled or is lethargic,
            see Box 24.1 on intensive care of hatchlings.
              Most shorebirds are very easily stressed. A warm, quiet, environment and as minimal handling
            as possible are important to their success. Make sure new arrivals are warm and well hydrated
            before proceeding with a thorough physical exam. During their time in captivity, birds should be
            briefly examined each time they are weighed for feather condition, vent cleanliness, foot condi-
            tion, injuries, or signs of illness. See Chapter 1 for information on performing a physical exam on
            chicks.
              Always hold a bird by reaching around from the back. Birds must expand their chests to breathe
            and if they are held from the front their breathing may be restricted. Chicks are very fragile so be
            gentle, taking care that a chick does not suddenly jump out of your hand and fall to the floor.
            Because shorebird chicks must be able to run shortly after hatching, their legs are well developed
            from the start.


            ­ Common­Medical­Problems­and Solutions


            Metabolic­Bone­Disease
            Due to rapid growth and often extremely long limbs, shorebirds may be susceptible to metabolic
            bone disease (MBD). High calcium, low‐fat diets are very important in rearing long legged birds.
            See Chapter 17 for a discussion of this problem.


            Angel­Wing
            Wing abnormalities in the carpometacarpal area commonly called slipped wing or angel wing may
            occur for several reasons: deficiencies in one of several nutrients such as vitamin E, vitamin D 3 ,
            or manganese, excessive dietary protein, or overfeeding (Flinchum 2006). If this occurs, the chick
            should be moved into a larger enclosure to increase its activity level. Adjusting the diet so that a
            greater percentage is chitinous food, such as crickets and mealworms (waxworms and fly larvae
            are higher in fat), also may help. Food should be supplemented with powdered calcium carbonate
            and avian vitamins (Nekton‐S). The wing should be wrapped into normal position and checked
            daily for improvement in its alignment. If attempts to correct this problem are made promptly,
            correction  may  occur  within  3–5 days.  Be  careful  to  not  damage  growing  flight  feathers  with
            wraps.


            Leg­and Toe­Abnormalities
            Stilts and avocets seem to be particularly susceptible to foot problems, such as drying, cracking,
            and pressure sores. Keeping the substrate clean and soft and offering clean wading dishes and
            pools are important factors in preventing foot problems. Splayed legs and curled toes can also be
            an issue. The proper substrate is very important to prevent this. They need to have good traction
            and not slide around.
