Gov. Charlie Baker isn’t ready to play chicken with lawmakers, taking to Twitter to rattle cages over a standoff on legislation that would ensure the state’s residents still will be able to buy eggs after the New Year.

“Everyone is already paying too much at the grocery store and not addressing this egg supply issue will further drive up costs,” Baker tweeted Wednesday. “I urge lawmakers to reach consensus soon before these rules go into effect in January.”

The House and Senate already each have voted in favor of changes to a voter-approved law setting more humane conditions for egg-laying hens, but a six-member conference committee has not reached agreement on a handful of details in the bill, delaying the proposal’s passage.

“The House is committed to ensuring consumers continue to have access to affordable egg and pork products,” House chair Carolyn Dykema said. “The conference committee is in active negotiations and we remain hopeful that there will be no supply disruptions as a result of this voter-approved animal welfare law.”

In 2016, Massachusetts voters overwhelmingly approved a ballot question imposing new standards on the treatment of animals used to produce eggs, pork and veal. That law, which requires each hen enclosure to have at least 1.5 square feet of floor space per bird, will take effect on Jan. 1.

Sales of eggs produced by hens in smaller enclosures — regardless of whether they are in Massachusetts or from another state — will be prohibited here when the new regulations start.

Laura Hagen, Massachusetts state director for the Humane Society of the United States, said the legislation “provides enhanced cage-free conditions for egg-laying hens that represent significant upgrades to their welfare, and it also ensures that millions more egg-laying hens will be covered by the protections established by the voters in Question 3.”

If they reach an agreement, they will need to ensure it can secure unanimous support in both chambers.
