Two of my F-4 hens that I used (and will probably use again) had Columbian markings and I did not hatch any this year that did not have the correct barring, most have too much though. If I had more choices, I would not have used those hens but I only had the four I deemed breedworthy and the two I sold to you. My guess is the Cocks used helped to get the correct barring or maybe by F'5's of a recreated line it just happens, I don't know. My uncle in law made a very good living for 25 years breeding champion game cocks. He said by F-5's you should be seeing apples for apples in type and colour if you have made the correct breeding choices. There is the clincher......... And, maybe not so in a recreated line.
Yes, obvious culls are obvious, many for the malformations you listed. I think a crooked keel can be felt early on, I have only ever had two birds in all the years with this fault. One was a Welsummer Cockeral who was culled as he was a "attack the hand that feeds you" personality and I did not notice the keel till we butchered him. The other was only a month old when I noticed it. Kept him till four months to be sure and to be a good size for eating and it was still crooked.
I also feel we should be culling for the slower maturers, at what age to make that call I am not sure. Does anyone else have some input on this?
Still trying to figure out this wing thing. It maybe something we can cull for early or maybe it is just slow development of the feathers in some of the birds and will resolve itself in time/age with some of the birds. Not sure how long to give them.
I'm feeling slightly more optimistic this morning.
If the three F4s I started with were good enough to breed, then anything that's even a slight improvement will be worth breeding. As long as I have anything that is an improvement, and I honestly have zero clue how to determine what is an improvement. I only took two crummy photos of the F4s when they were on their way here, which was last October ... I have more photos from December when the first pullet started to lay. I'll use those photos for comparison purposes, and be extra vigilant about "dirty" looking feathers. But I'm still super confused about how to compare the birds.
So between the two of us (Zanna and me) if we do decide to send my Mr. F4 back to you, we'll have to decide if I use one of your F4 cocks as the mate for my F5 pullets, or if I'll breed my F5 pullets to one of my F5 cockerels. I'm perfectly happy putting "our" best male with "our" best females for next season, no matter which one of us starts out with which birds or where the actual breeding/hatching takes place. And from what I gather, it doesn't really matter if they are F4s or F5s at this stage because they are all still very closely related. I'm perfectly okay with you doing the breeding and hatching of the best birds. I don't cull as hard or as soon as you do, but I also don't hatch as many chicks or have as much experience assessing birds.
If I end up with just one pen of breeders here that's fine ... it would mean I wouldn't have to divide my breeding coop and could run things next year exactly like we ran them this year. Another year of practice. So I do want something potentially useful to work with.
About breeding for more precocious birds. One of my ideas for this year was to breed whichever pullet was the first to lay. Now I'm not so sure that's what I'll do. I did nothing to mark or chicks so I'd know which hatch they were from, so can only guess at their relative ages. But this is for sure something I'll be working on eventually if I'm able to continue with this line.
The wings on the cockerels is very tricky as it seems to manifest just when it would be ever so nice to send some the cockerels off to pre-freezer camp, and then there is a wait of several weeks to assess the wings. These cockerels seem to go through a very awkward stage. The silver lining of that wait seems to be that early brassiness also develops in that wait time ... ?
I haven't noticed any wing issues on my females here. We'll have to look at that, too.
