I ordered an assortment of chicks from MPC and I have a chick that had a swollen foot/ankle on her left leg the beginning of this week and thought she might have gotten injured. Well this morning I noticed that she isn't walking nicely at all, and she now has a very swollen knee/hock joint on her right leg along with the swollen foot on the left leg! What is wrong with my baby? Do I need to completely separate her? Do I need to do the dreaded thing and put her down? Please let me know as I have 15 other chicks that she is currently with and I have 23 bantam chicks in another brooder but in the same room as her. Thank you in advance!
