Howzit!
As the only person answering who actually lives in Hawaii and has repeated dealings with the Ag Dept., hereʻs the skinny. Eggs can be imported, but only from certified hatcheries with their own Stateʻs phyto-sanitary certificate attached. They are usually shipped by Priority Mail without problem. Likewise, day old chicks come in all the time. I order from Ideal, but my neighbor has had good luck with Murray McMurray. With hatching eggs costing almost as much as chicks, Iʻd go with the chicks. BTW, for 25 chicks from Ideal, the total shipping, handling, phyto cert. fee, etc., all comes to about $15 total. A real bargain.
