Do fowls when crossed throw odd and unexpected colours like pigeons?
Down Bromley Kent
My dear Sir
Many thanks for your most kind offer of the Eggs of the Rumpless Polands.— Will you be so kind as to send them by enclosed address as soon as you conveniently can, as we have a Hen ready to sit: it is really a shame accepting so many as a dozen, but I shall by having so many be able to see whether the Breed comes true as Rumpless.— Have you found them true??
With respect to the Scanderoons my pair has never laid an egg since those which
produced your pair. I am ashamed to say that I do not know
Cock from Hen.— Would you like to have the pair to
try to breed from; I sh
I have now got some Fowls from the Dyaks of the interior of Borneo sent me by the Rajah: shall I send them to you at same time?
Will you tell me what colour your turbits are which have thrown the dark tails: you are quite right it is just the class of facts which interest me: —in Mayors' time, I see that the red & yellow Turbits had white tails.—
I know I have your note, (but I have mislaid it) about the colour of Pigeons & their down.— Will you kindly tell me briefly the fact again? By the way I wonder if I have any Pigeons which you want: do you want black Barbs? Just mention what you want, & then I can see whether I have anything to suit.—
I have not yet got your Poultry Book; though I presume that
it is lying at my Brother's (for I have not been for a long time in London; my
health having been of late very indifferent), & therefore I do not know whether
you describe the plumage of chickens in their down: Dixon describes most of them; but the chicks of Gold & Silver Pencilled
& spangled Hamburghs are not described, & I
I wonder whether Fowls when crossed throw odd & unexpected colours like Pigeons do.— Do you know of any such facts? For instance if you were to cross black Spanish with Black or Silver Polands, do you suppose ever red or other marked new colour would appear?—
Let me have a line about the Scanderoons; if you do not choose to have the pair to breed from; I then will try & make out which is Hen, & send her, & I think I will kill the Cock.— Also say shall I send Borneo Fowls?
Pray believe me | My dear Sir | Your's very sincerely | Ch. Darwin
P.S. I have just been looking at Scanderoons, but I really fear the Hen is ill, for I think I know which is which.— The servant in charge reported 3 weeks ago (I have been from home last fortnight) that one of them looked moping, & so she certainly does with wings a little drooping; & that may account for the pair not having gone to nest this spring.— but I will observe more carefully during this coming week
- f1 2090.f1The date is suggested by the relationship to the letter to W. B. Tegetmeier, 18 May , which it precedes, and by CD's reference to having been away from home a fortnight. CD returned to Down from Moor Park on 6 May 1857 (‘Journal’; Appendix II).
- f2 2090.f2Tegetmeier had earlier promised CD a rumpless chick (see letter to W. B. Tegetmeier, 11 February ). CD was collecting specimens of the young of various breeds of fowl to note the first appearance of the typical characters of each.
- f3 2090.f3See letters to W. B. Tegetmeier, 23 June  and [19 July 1857]. CD found that the rumpless Polish fowl did not breed true.
- f4 2090.f4CD had sent Tegetmeier a pair of Scanderoons in August 1856 (see letter to W. B. Tegetmeier, 30 August ).
- f5 2090.f5According to Eaton 1852, it was not easy to tell Scanderoon cocks from hens: ‘in this point the best and oldest Fanciers have been sometimes deceived’.
- f6 2090.f6See letter to W. B. Tegetmeier, 18 May .
- f7 2090.f7James Brooke, raja of Saráwak, had sent CD several specimens of domestic fowls kept in Borneo.
- f8 2090.f8CD collected such facts as instances of reversion to what he considered was the progenitor of the races of domestic pigeons, Columba livia. See Variation 1: 195–203.
- f9 2090.f9[J. Moore] 1765, pp. 127–8. This book is an anonymously edited, revised, and enlarged edition of a treatise on domestic pigeons originally prepared by John Moore in 1735 (J. Moore 1735). The later work was inscribed to John Mayor, by whose name it was sometimes known.
- f10 2090.f10CD cited Tegetmeier in Variation 1: 170 concerning ‘a curious and inexplicable case of correlation, namely, that young pigeons of all breeds, which when mature become white, yellow, silver (i.e. extremely pale blue), or dun-coloured, are born almost naked; whereas other coloured pigeons are born well clothed with down’.
