Marek's is the bane of my existence. I lost an entire shipment of beautiful Speckled Sussex chicks to Marek's. It has multiple forms, and once a bird becomes symptomatic it is almost always fatal (the percentage of those surviving it is fractional, and most of those birds are compromised for life). Vaccinating all birds will not eliminate it eventually, as it is carried by wild birds. Chicks must be vaccinated in the first 48 (? might be 72, I could have mis-remembered this) hours of life, the vaccine is only good for 48 hours once mixed with the diluent, and the vaccine is live vaccine, meaning vaccinated birds shed the virus for life, exposing all other birds to it. There are many schools of thought on this disease, but after consulting breeders with decades of experience I opted not to vaccinate chicks. My thought was that if there are birds who are naturally resistant and birds who are not, I will never know which are resistant if I vaccinate; if I do not, the birds that live and thrive past 6 months of age are resistant and should pass that resistance on to their offspring.
I had decided not to vaccinate my chicks but my older birds were vaccinated at the hatchery and I got them as POL. could they give my chicks mareks? I have two coops so they can be separate flocks but I did want to breed my roos to my older hens
my hatch finished at 9 pm ..set 17 ..had 3 clears ,,1 quitter,, 13 to lockdown hatched 12..one never piped or tried fully developed not sure..someone in this thread asked about wood heat with the bator going . I had my wood heater fired up part of the time although I just use it as supplemental to my electric heat pump. I did a dry incubation with humidity ranging from 15 % to 25 % for the first 16 days. I did mist the eggs twice daily with a spray bottle of water kept in the bator so It was the same temp . then on day 16 I filled the water pan and had humidity readings of 45% - 50% then on lockdown I added two sponges and raised the humidity to 70%. this worked better for me than keeping the humidity up all the way as I have done in the past. I will note here humidity is relative (pun intended ) to where you live , the humidity in your home , the humidity outside your home, and the temps of both. what works well here might not work well at a different location. thank Ron for keeping up with this thread great job. thanks to all the great participants and posters with tips and advise and stories about our lives and how our hobby affects it . I wish everyone the best with their new knowledge and
