Hi everyone. Newbie to backyard chicken raising...... We have just bought three 20 month old brown shavers home today. They have been free ranging on a farm. When we put them in the coop, one couldn't stand up - though she's gradually gotten on to her feet, but is all hunched up and just wants to sleep. Her crop is dirty (dark brown) and she isn't eating or drinking. The seller said she was fine yesterday and laid as normal, but doesn't know if they've been wormed as she was selling on behalf. Not sure where to start with helping her. We are going to put her in a warm bath for now and will check for egg binding, but don't know where to source things like anti-biotics, liquid calcium etc. and what the doses would be. Any help gratefully received.
