I have been having some problems with my week old broilers. First thing is that some of them are having leg problems. They walk on their shins instead of their feet, some of them also have curled feet. I put a splint on some of them but I'm not sure if that's helping. Another problem is that two of the chicks have poopy backsides and one of them was very clogged up. I gave them yogurt. While I was watching them, one of the chicks pooped but as soon as it was done something red emerged from its vent. It looked like intestines. I'm very concerned. Thanks for your time.
