My 8 month old Easter Egger Goldie is limping on her left foot. Just noticed it today. Could it be Mareks? The others are not pecking on here and she is running around eating and drinking so I am not isolating her. If it is Mareks then isolating wouldn't be much of a help, because of incubation time all of them would have it, right ??? I checked her feet and they look normal, no obvious injury and her eyes, comb everything else looks fine. How long should I wait ...... I am just afraid that it might be Mareks and I have to cull her or my entire flock is infected !!! HELP, don't know what to do.
