Thanks. The test-cross for foot color is an excellent idea. Will keep an eye out for some appropriate hens for test-crossing. I could use some more hens in the laying flock anyway. Might as well be something I can use to test-cross with. Was hoping to fill the laying ranks with extra pullets from this batch of chicks, but the numbers didn't work in my favor.

i only raised Java's for a short time so am no expert... but ill speak to what i know from chicken breeding in general... if there is 2 birds in there that have yellow showing they pro all carry it... it can be really hard to pull yellow legs out of white legged birds... in my white Emps last year the adult flock was 50% yellow and 50% white legged and i hatched 95% white legs so i decided to cull down to only the yellow legged birds... this year with a yellow legged male and 3 yellow legged hens i am still only getting 50% yellow legged offspring... so if you insist on keeping his line pure i would find a bird with yellow legs that is totally different (like a white leghorn) to use in test matings... only cull roosters that have a bad fault and keep say 10 to use... breed one at a time to some white leghorn hens and hatch say 15 chicks... u can normally tell white from yellow within a week or 2... if they all have white legs cull the male if there is some white and some yellow than he can be kept for use... only do single matings your 1st year and hatch about 20 chicks from each male over each hen... i would shoot for 1 keeper male for each female to give you the most diversity u can get... keep very good records of what chicks came from what parents and then evaluate them accordingly...
if you know that all your males and all your females are at least carrying yellow than u should be able to keep it going in the line while u build the barn...
on the smaller females i don't think u will see there full size potential until at least 9 months so i would not worry about it to much just yet...
