I have 11 week old Wyandotte pullets that I hatched. I have 18 bird and I feed them grower finisher from TSC. They are in a new coop and run. I give them time to run in the grass, but I have hawks in the area so I watch them. Today I saw one of them having difficulty walking. I pick her up and she seems fine. I took her out for time in the grass and she just set there. I then let the other birds out. I watched them very closely. I then saw another bird having difficulty. What can I do? What information do you need to help me. I am sick!! They are my babies. Please help! Any suggestions will be welcomed.
