HI there. I have 3 new chicks that I got from TSC One of them has a really inflamed vent and poop stuck to it, when it poops the poor little thing strains so hard. I tried to get some of it off but its whole vent is huge and red. The second chick isnt as bad but its definitley the same problem just not as bad The third chick looks perfect. What do I do??? HELP !
