So ~97-99° Fahrenheit? When I incubated mine I used 99.5 and while the Brahmas were 11 hatched of 13, the Silkies were 4 hatched of 12. Could that temp be my problem? (All were shipped eggs but all developed for at least a little while.)
Well, yes, but there are degrees of "large." My Brahmas are LF, but so are my Dominiques, so I thought you might have something more specific you were aiming for. Or maybe you're just aiming to make the biggest silkies you can and keep moving them toward faster-growing/bigger birds. Your big guy...
