Hi! I'm new to chickens, we just got 6 from someone a couple days ago. They are 3 and 5 week old silkies. Started feeding them the starter grow food. All poops looked normal to me then the next day some were bloody.... Not sure if they are ALL like that but I'm not seeing many normal looking ones now. Lady I got them from said she kept two from same pen and they are fine. Also thought I heard what sounded like a sneeze a few times. They are staying in a cattle trough in our enclosed garage. There are two ceiling fans in there as well, wasn't sure if that would bother them being on too. I assume I need to get a dewormed? Thanks for any help!
