Laboratory notebook containing records for poultry breeding lines hatched in 1909 and 1910.

The notebook begins with records for chicks which hatched between February and December 1909, labelled W 1-338 [pp.1-156]. Chicks hatched between April and May 1910 then begin on [page 157r] with a new numbering sequence, W 1-144.

Entries for each bird include notes on colour, comb, and other physical characteristics (e.g. abnormal digits), state of health, and date of death, etc. The record for 1909 birds W 10 [page 5v], W 109 [page 54v], W 176 [page 88r] and W 213 [page 106v] includes drawings of a shoulder joint and feet. A note for 1909 bird W 324 [page 153v] states that it ‘swallowed a glass headed pin’. Entries are in two handwriting styles; the second may be Punnett's.
