I've never heated or monitored the humidity on my mealies, I've been raising them on and off for years. They may grow slower but it doesn't take long to get a colony going. If you wanted to heat them though you could look into heat tape like is used for reptiles. You'll want a thermostat and...
I'm not familiar with the black skin gene, but it is sex linked. That is probably were you read about it. I can't tell you more because I don't know the details.
If you flood the tank with CO2 the animal will freak out. It is not calm and peaceful. When I've put animals down with it I put them into the tank and then very very slowly start to pump in the CO2. Once they pass out I flood the tank(for euthanasia) Also, when you use the vinegar method the air...
I've read about this in buckeyes, with some chicks having a different color down. I don't know what genes are involved. I think one color isn't desirable but it has been a while since I came read about it.
Remember that birds and mammals are very different and what works well on one may be very bad for the other. Also CO2, I do have experience with using it. Not for birds, but with small animals. I started out with the vinegar/baking soda route, I wouldn't recommend it. IF you must use it go with...
While it is possible for a pheasant and chicken to cross that chicken is not a hybrid. It isn't very common and most chicks end up dying before hatch, if they do hatch most don't live long. Your chicken has silkie feathers, that trait is recessive and needs two copies to show. One from the...
Blue and lavender are two different genes that both affect black. I've heard it is best not to mix them, I think because they can be hard to tell apart. You can also have blue lavenders. Your birds would need two copies of lavender for it to show, I believe that the cross would be either black...
