i have a total of 27 chicks that are 4 days old. One of the cornish chicks is very sleepy and has slow breathing. Its been doing this for the past 8 hours now and isnt very responsive when pecked at by the other chicks. walks VERY slowly if does walk at all and only goes a few inches before falling back to sleep. Should i seperate it from the chicks or just give it extra attention and keep an eye on it?
