 The eggs are described as like those of a Phylloscopus warbler ( white with some brown speckles ) , unlike the eggs of the common firecrest , which are pink with very indistinct reddish markings at the broad end . The clutch size is unknown , but believed to be smaller than the 7 – 12 of the nominate race of common firecrest . The female incubates the eggs for 14 @.@ 5 to 16 @.@ 5 days to hatching , and broods the chicks , which fledge 19 to 20 days after hatching . Both parents feed the chicks and fledged young .
