I have a question for you CL folks - has anyone had to go through the process of breeding for resistance for Mareks? If so, can you share your experience with regard to how many you need to hatch/grow out for that purpose, and at what age you get a sense of it (I'm assuming POL but I lost one about 10 weeks after POL soooo...)
I have CLs from the earlier lines - all I know is that they are not Rees. I'm trying to make housing and family group plans, and as I have other breeds I'm working with, I'm trying to figure out what numbers are necessary for that goal - I have decided that I always want CLs in my yard, and I want to know how many I need to keep around from a given hatch/spring in case some start to drop (I've got 19 right now - 11 girls, 8 boys). The boys are being impossible, I love my current rooster, and I would love to not keep any of them. The good news is that Dumbledore (obtained from ChicKat) appears to have an iron constitution - living with a pullet with ocular Mareks (so likely shedding a lot), and also undergoing a massive stress with the dog attack, and no sign of Mareks so far. I need to check with her to see if he was vaccinated or not (about to PM her). Then I have one hen that was vaccinated, also living in a shedding coop and also fine. I have the offspring from this pairing of the two disease free birds as my primary group I'm working with (4 girls two boys), but also some from the other affected pullets as well - which, though coming from susceptible genetics, also probably benefitted from maternal antibody... I was going to put the pullets in the egg laying/olive egger coop.
(I know that Mareks is very common, but if you don't want to post about it in your flock here, please PM me - just looking for advice).
Thanks in advance!!!!
