I have 5 silkies a little over a month old about a month and a week and one of them lays down quite a bit. She will walk normally to the rest and just lay down and gotta like slouch to the left or right. She is eating and drinking just as much as the others and she plays with them and runs around but she doesn't "graze"? As much as the others. When she was a chick she was dropped 3 times ( I know that makes me sound horrible but these are my first chickens) so could she possibly have a disability or internal injury or is it just her personality? She is the brownish chick in the pictures and the pictures are from different ages of there lives.The last two pictures are from yesterday. Any help is appreciated thank you all.
