I have had my Rooster for 5-6 years and he is like family to us. a few weeks ago I found him in the chicken pen not being able to walk or stand. I tried helping him back up but he would just fall over. So, now we have him in the house in the cage and he still cannot walk or barely stand. He has a hard time breathing at times, his comb is discolored and laying over a bit. He also seems to be having a hard time pooping only liquid or gas comes out. He will eat some and i give him water through a little pipet. But I do not know what to do or give him and I think his time is running short though he is still pretty peppy. WHAT DO I DO?
