Hello friends, I have three 2.5 week old Pekins. Today 2 of them started sneezing, and breathing very quickly, occasionally with open mouths. Also, one has different waste now. Before it was soft, formed and grainy, now looks like dark babyfood. Do they have a respiratory infection? Additional info to help you help me! -Got them at TSC -In a 2.5 ft, by 5 ft enclosure, bottom of the enclosure is 2 inches of Hay, with a few aspen shavings, on top of a shredded newspaper layer and bottomed by brown paper bags (makes cleanup so easy!) -Still under heat lamp, around 80, although they often sit away from it -Plenty of water (3 of them go through 8+ quarts a day) -Currently eating unmedicated Dumor chick starter/grower 20% (recommended by TSC associate) and organic Golden delicious apples -Feed specs: Crude Protein (min.) 20.00%, Lysine (min.) 1.00%, Methionine (min.) .50%, Crude Fat (min.) 2.50%, Crude Fiber (max.) 4.50%, Calcium (Ca) (min.) .70%, Calcium (Ca) (max.) 1.20%, Phosphorus (P) (min.) .65%, Salt (NaCl) (min.) .25%, Salt (NaCl) (max.) .75%, Ruminant meat and bone meal free. -Nostrils are clear -Got their baths yesterday. Thanks!
