Gold Duckwing Welsummer cockerel

Yesterday I noticed the young Gold Duckwing Welsummer cockerel was limping a little. This morning more so. He appears in fine fettle and is still eagerly chasing and treading the hens. Tonight once he has gone to roost I'll check under his feet for any sores, although I have a feeling the injury is more muscular. If so I will probably house him for a few days, along with a couple of hens, to restrict him and also to keep a closer eye on him. I am hoping to use him next season as the breeding cockerel of my second line of Gold Duckwing Welsummers.
