语法分析：本句的主干是由连词but连接的并列句：These eggs are still labeled organic and animal-friendly but they’re also from birds that live on farms using regenerative agriculture意思是：这些鸡蛋仍然被贴上了有机和动物友好型的标签，但它们也来自于使用再生农业的农场。除此以外，本句还包括两个定语从句和一个同位语从句，都是修饰成分。其中which are making their debut now on shelves for as much as $8 a dozen 是定语从句，修饰eggs，意思是“目前(这些鸡蛋)在货架上首次亮相，售价高达8美元一打”;另外，that live on farms using regenerative agriculture也是定语从句，修饰birds，意思是“(它们)生活在使用再生农业的农场里”;破折号后面的special techniques to cultivate rich soils that can trap greenhouse gases是同位语从句，解释说明regenerative agriculture，意思是“培育能吸收温室气体的肥沃土壤的特殊技术”
