The aim of present study to compare the egg weight characteristics of quail, duck and brown strain chicken using the hotelling T2 statistics and to study the pattern of charateristics via correlation coefficient. The egg weight was heaviest in duck with average weight of 61.78 g followed by brown chicken strain with average weight of 61.6 g and quail with 10.8 g. Shell weight was heaviest in brown strain with 6.58 g, followed by duck with 6.14 g and quail with 1.11 g. Yolk weight was heaviest in duck with average weight of 22.4 g, followed by brown strain chicken with average weight of 16.09 g and quail with average weight of 4.31 g. Albumen weight was heaviest in brown strain chicken with average weight of 38.9 g followed by duck with average weight of 16.38 g and quail with average weight of 4.93 g. Correlation matrix obtained showed that the pairs of weight characteristics compared were highly and linearly correlated at 1% level of significant. Analysis of variance was carried out to compare the weight characteristics of eggs and it was discovered that the weight characteristics (egg weight, shell weight, yolk weight, albumen weight) of the three poultry species were significantly different. Pair wise comparison were done using LSD and showed that: the mean of the egg weight of brown strain chicken and duck do not differ while other pair comparison differed. All pair comparison of the mean shell weight differed significantly. The pair wise comparison differed in mean yolk weight and in albumen mean weight. Pairwise comparison were carried out using Hotelling T2 and it was discovered that the mean weight of the egg characteristics differed in the birds.
