Hi everyone - we are new to raising chickens though we are mature in age. To put it mildly, we have been overtaken by the desire to see our little flock healthy and growing every day. We have 21 mixed varieities that are all together in a great coop and outside run. All of them are doing very well except one little girl. Today we noticed that her vent was kind of sticking out and she was picking at it. We brought her in, cleaned the vent with a Q-tip and sprayed it with Silver Sol - which is a mild anti-bacterial. A little while later, we saw her picking at it again. What is the problem? All the others seem healthy and they're growing like weeds. We are very concernced about this one little lady.
