Hi, We will be ready for our chickens in a few weeks. We are excited about this project We also have a large flock of homing pigeons. We are fairly experienced with them and their care, having over 100 of them for over three years at this stage. Our question is -------- the pigeons and chickens will not be loose simultaneously. However they could separately be loose even though at this stage we do not intend to let the chicken out of the chicken tractor which is portable. And of course, they will NEVER be in each other's living quarters. Since we'll have both chickens and pigeons, we wanted ask if there might be special health concerns since we'll have two different types of birds on site. Also, we plan to purchase 19-20 week old pullets ---------------- what vaccines should I ask about? Thank you, in advance, so much for your help.
