  1. 1. Abnormalities In Hatching Chicks Mujahid Hussain
  2. 2. Crippled ChicksHatching chicks are disabled in feet or legsCauses:1) Improper incubation temperatures (usually too high)2) Improper egg position & turning during incubation3) Low humidity during incubation4) Improper ventilation5) Heredity6) Slick hatching trays7) Improper nutrition of breedersCorrective Measures:1) Follow recommended incubation temperatures2) Increase incubation humidity by increasing water evaporation3) Set eggs with small ends down.Turn eggs at least 3 times daily4) Proper culling & breeding practices5) Use trays with wire floors6) Provide a well-balanced nutritional diet to breeders
  3. 3. Crooked ToesHatching chicks have bent toes or any other irregular shapeCauses:1) Improper temperature in setter2) Improper ventilation3) Improper nutrition of breedersCorrective Measures:1) Follow recommended incubation temperatures2) Provide a well-balanced nutritional diet to breeders
  4. 4. Spraddle LegsChicks hatch with splayed legs.The feet are pointing to side instead of forward making walking difficultCauses:1) Temperatue fluctuations during incubation2) Difficult hatch3) Brooder overcrowdingCorrective Measures:1) Follow recommended temperature settings2) Provide proper conditions for normal hatching
  5. 5. Closed EyesChicks hatch with closed eyes.Baby chicks have eyelids crusted or glued shutCauses:1) High temperature in hatcher2) Low humidity in hatcher3) Improper nutrition of breedersCorrective Measures:1) Follow recommended incubation temperatures2) Increase incubation humidity by increasing water evaporation3) Provide a well-balanced nutritional diet to breeders
  6. 6. Missing EyesChicks hatched with no eyesCauses:1) High temperatures2) Improper egg handling during incubationCorrective Measures:1) Follow recommended temperature settings2) Proper egg handling during incubation i.e. egg position,egg turning
  7. 7. Sticky Chicks (1)Hatched chicks have albumin sticking to themCauses:1) High temperature2) Low humidity3) Too late egg transfer4) Inadequate ventilation5) Inadequate eggs turning during incubationCorrective Measures:1) Follow recommended temperature settings2) Increase humidity by water evaporation3) Egg transfering must be at its proper time4) Proper ventilation5) Proper egg handling
  8. 8. Sticky Chicks (2)Chicks hatch with albumin sticking to shellCauses:1) Too high temperature (20-21 days)2) Broken eggs in the tray3) Inadequate turning4) Excessive ventilation rateCorrective Measures:1) Follow recommended hatcher temperature settings2) Proper egg handling3) Adequate ventilation

Chick Can’t StandHatched chick is unable to stand.No splayed legsCauses:1) Imrproper temperature in hatcher2) High humidity in hatcher3) Malposition during incubation4) Improper nutrition of breedersCorrective Measures:1) Follow recommended temperature settings2) Provide normal humidity level3) Proper egg handling during incubation4) Provide well-balanced nutritional diet to breeders
  10. 10. Rough or Un-healed NavelsChicks hatch with unhealed navels.May be wet or dry.Causes:1) High temperatures (1-19 days)2) High humidity (20-21 days)3) Navel infection (Omphalitis)4) Improper sanitation in incubator5) Improper nutrition of breedersCorrective Measures:1) Follow recommended incubation temperatures2) Keep humidity level at normal3) Clean & disinfect incubator and hatching units between settings of eggs4) Proper sanitation in incubator5) Provide well-balanced nutritional diet to breeders
