I've heard frizzles are a bit wacky because of there changed gene, but I am wondering what exactly this "wackiness" is. My frizzle chick seems to have less of a want for treats, and when she pecks something she always aims to the right and misses. but she seems very alert, playful and happy with no signs of paralysis or blindness. I know that my chickens are carriers of marek's, but i got my new chicks vaccinated and quarantined them for three weeks. Should i be worried?
