Tonight when I went to put my chicks to bed I heard a weird noise coming from the creep feeder/brooder. I peeked in and saw my little 3 week old splash silkie breathing weird and making this odd coughing noise... She was looking around and saw me, was alert... but the coughing/whistling concerns me.... What can I do to help her?? Should I separate her from the rest? During the day she and a few of the very small babies like to stay inside the brooder box while the bigger chicks sneak underneath and explore the coop and run. So she isn't disturbed much during the day... I bought her from a breeder where most of my other chicks are from a hatchery and have had vaccinations against Mareks... I gave all of my chicks electrolytes for their first 3 weeks and recently stopped them... What can I do? Electrolytes? Antibiotics? Separation from the others? (I'm afraid that might stress her out...) Thanks!!!!!
