Looking for advice on a long-term breeding plan. I have 22 black javas from Duane Urch that are now 12 weeks old - still way too young for culling but I'm thinking ahead. I want to maintain and improve this line without introducing other lines into the flock. Of the 22 birds only five are pullets and at least fifteen are cockerels.
With that many cockerels I may have to cull a bunch before they are a year old. There are a couple of cockerels with good size and decent body type. All five of the known pullets are very small. A couple of the pullets have good wide tails, relatively broad backs, and generally decent type. They're just small. With dainty shanks, so I'm not expecting a significant growth spurt later.
Question #1: How hard is it to improve size using small females and large males? Feedback on this issue would help me decide if I need to import some other Urch line pullets, since all of my pullets are on the small side. If I just use the birds I have, size is going to have to come from the males. Can this be done?
Plan is to build the barn and then paint it, so I want to focus on getting the size and body shape right first - BUT if I'm going to "paint" the barn later I've got to have some "paint" to do it with! Javas must have yellow soles on their feet. Lack of positive yellow is a disqualification. From what I understand, yellow soles is a recessive trait. I've only got two birds with positive yellow soles, and they are two of the smallest birds and not necessarily the best body type. Most of the rest have white soles. I have no idea how many of those white-soled birds may be hiding a yellow-soled gene.
Black Javas are supposed to have dark brown eyes. I've only got two birds with truly dark brown eyes. The rest have much lighter, muddy greenish-brown eyes. Those light eyes may darken a little over time, but I don't expect them to get truly dark brown.
The two best-shaped and largest cockerels have light eyes, pale grey shanks and feet with white soles. If I use those large, well-shaped but poorly-colored cockerels I am likely to lose the dark eye and yellow sole color genes from those family lines as I "build the barn." I don't want to cull out the two dark-eyed birds and the two yellow-soled birds, even if their body type is not the best, because those are the only birds that I know are carrying the necessary color genes I will need a few years down the road.
Question #2: Should I hatch out some chicks from the dark-eyed and yellow-headed birds anyway, just to keep those color genes available in the flock, while I work on improving the "barn" in a couple of specific family lines - knowing that the "barn" improvement will likely remove several of the critical color-related type features from those family lines?
Question #3: How persistent is crow-headedness? A few of the birds in this flock look a tad more crow-headed than I would like, including the two dark-eyed birds. Is crow-headedness something I can breed out fairly easily if I need to use a more crow-headed bird later to bring back the dark eye color? Or is crowheadedness something that takes over the flock if you're not careful?
Thanks for any insight you can give me. It will help me make some critical decisions over the next few months.
