I found one of them drinking the water this morning! I also got the other to "drink" my adding water to chick food and making it into mush. The both LOVE it! Hopefully that'll stimulate them to eat/drink normally.
She still has white stuff running down her bum, it wasn't dripping when I saw her, but she did have a dribble trail down her bum.
Now to figure out where they got it from...I've brought in chicks from several places but I don't see any sick chicks and mama is fine. I'm going to be disinfecting the coop today and might move them back in today or tomorrow depending on how the 4 remaining girls look.
Edit: I'm giving the antibiotic water to the 4 "healthy" ones right now, is this a good idea? I'm also going to be providing plain yogurt to EVERYONE, including the chicks. I'd also like to give ACV in the chicks' water, but how should I go about giving them their vitamins/electrolytes then? Can I sprinkle it in their food? Or should I skip the vitamins/electrolytes and stick with the ACV. I am NOT giving antibiotic to the chicks (except for the two I brought into the house for sneezing...it's in mush form as well) unless I have to.
