Sometimes when I access chickens the menus are blank. Just the 'info' button is visible, all the other items are not there (as in totally missing, not that there is a long menu with menu items blanked out). If I repeatedly try the same chicken eventually the full menu appears and I can squeeze the little fellas hard...
At first I thought it was limiting interaction with chickens who were flying which kinda made sense, but I've seen it with walking chickens as well, so it makes more sense to me as a bug now...
