A fluid ejection device may include fluid actuators, ejection chambers adjacent the fluid actuators, nozzles extending from the ejection chambers, and fluid feed holes to supply fluid from a fluid supply passage to the ejection chambers. The fluid feed holes have ports connected to the ejection chambers. The ports are sized to pass bubbles formed by the fluid actuators out of the ejection chambers.
