Rice works through the physiology of egg laying, the pigment that drains from a bird's beak and shanks as the season goes on, the timing and pattern of the moult, the shape and set of the head, and the way production spreads across the year.\u003c\/p\u003e\u003cp\u003eThe premise still holds. Birds on the same ration return wildly different numbers of eggs, and a practised eye can tell which is which. Written while American egg production was industrialising fast, it is also a clear window on how the modern laying flock came to be chosen.\u003c\/p\u003e\u003cp\u003eThis edition features: \u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eThe physiology of egg laying and what a season of production does to a bird's pigment and plumage\u003c\/li\u003e\n\u003cli\u003eA method for reading the moult, the head and the body to judge what a hen will return\u003c\/li\u003e\n\u003cli\u003eGuidance on selecting the birds to breed from and removing those that do not repay their feed\u003c\/li\u003e\n\u003cli\u003eUseful background for anyone with a laying flock and for readers of agricultural history\u003c\/li\u003e\n\u003c\/ul\u003e\n            \u003cdiv\u003e\n\u003cstrong\u003eNumber of Pages:\u003c\/strong\u003e 444\u003c\/div\u003e\n            \u003cdiv\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 0.99 x 8.5 x 5.5 IN\u003c\/div\u003e\n            \u003cdiv\u003e\n\u003cstrong\u003ePublication Date:\u003c\/strong\u003e January 12, 2011\u003c\/div\u003e\n            ","brand":"BooksCloud","offers":[{"title":"Default Title","offer_id":67872617791640,"sku":"9781446528495","price":53.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0759\/8830\/4024\/files\/3papLHm-RL9781446528495.webp?v=1793613122","url":"https:\/\/thepinkflamingobookstore.com\/products\/judging-poultry-for-production-paperback-1","provider":"The Pink Flamingo","version":"1.0","type":"link"}
