Hello new here we purchased our chicks week ago we had 6 but we lose one she was tiny and didn’t survive. But then we have this one ( itty) black one. She’s been fine other then her little peeps Thur out the day she is fine eats drinks sleeps she did have some pasty butt but not now. But today she seems stressed out. The temperature are warming up around here so yesterday the coop was way to hot which I though the temperature was fine today I can’t get her calm down. Should I adjust temp for just her ? I don’t know she always trying lay or get under the wings of the others with her which as you can see they are way bigger. We was told they was 2 weeks when we got them last Sunday. Which should put them at 3 weeks ?? And should i still be adding the probiotics to the water ? Temperature is 87.
