I have a little 4 day old Americana in with my 6 day old welsummers and today I saw pink in the Americana's poop. Could this be coccidosis? I have sulmet, but have read that it is hard for them to process it, what should I look for to see if it is really coccidosis? I don't want to lose my babies to anything. Please help, they are all acting fine eating drinking and popping fine. Also I have them on chick stater medicated feed. Thank you so much for your help.
