My chick has been drinking and eating. She has not gone to the bathroom at all. Her vent is..pulsing? like she has to go to the bathroom (ive noticed other chicks doing the same thing) but nothing ever comes out. Her vent is clear, ive checked several times and even cleaned with a q-tip but still nothing. I dont know what to do. Shes only been eating chick feed and a little hardboiled egg yolk cause she wasnt acting good earlier either.
