Fun concept.
Only real niggle was one time the chicken capture bar was a bit quick for how long it took the HUD to show up. Maybe the movement was a bit slow, but I guess you don't want the player to outpace the guards, and it does get you into a more careful mindset.
I can see all kinds of wrinkles in a bigger game, like some chickens having more elaborate capture mini-games, or more complex routines for the guards.
