Well i just got done with testing of my birds who are sick, by the state vet here in AZ and from what the vet saw he thinks they have Mycoplasma gallisepticum infection which appearantly is going around here in AZ. aparently it doesnt do much to the chicken just gives them cough and weezy breathing but will spread to chicken to chicken.also read up on this i found out it affects hatch ability which probably explains why i have yet to have good hatches with lots development but few hatching. also was bummed that i have to go through another agency to get into more intensive testing (all he did was swab the mouth) and to get my NPIP certification. anyway sorry for ranting so much lol. anyone know any medicine that will get rid of this??? as many warned me the state vet usually says cull the birds this one didnt say it but he didnt recommend any meds either. also if anyone has experience with this infection or info please share. does it effect eggs for eating since it affect hatch ability?
