Hi, I have had my chickens for 3.5 weeks and they were 3-4 weeks old when I got them. They have been on 26% protein gamebird feed by manna pro and they are destined for freezer camp. 20 min ago I noticed one wasn't able to stand on its feet. I have since brought her inside and she's in my chicken er with a dark blanket over the cage, and I soaked some 18% protein all flock pellets, nutridrench water with some electrolytes and vitamins and gave her a dropper full of straight nutridrench. What else should I do?
