Once before I noticed one walked poorly. I left it be and it got better on own. couldnt tell it apart from rest. friday i was told one didnt walk well. saturday morning found it on side. stood it up and it walked poorly. pm eevryone going in coop but that one walking with difficulty outside, saturday am on side in coop. carried it outside tried to stand it up and seemed to stand ok. pm found it on side in a different spot. looked like on side for while marks on ground poopy but. checked legs look normal but when I stand it up it falls backward and lays on side. feet seem colder than other birds. will take inside to bath and sling it and see if it eats. please help if you can.
