I'm going to be getting a couple 4 months old (3 months old now) pullets in a month because it was cheaper to drive to get them then have them shipped. Should I have each of these birds in separate containers or would they be more comfortable together? After picking the birds up it will be about 8 hours on the road and in between may be an overnight stop, depending how tired we are. If we do decide to stop on the way back, its at my mom's house and she has a fenced in yard so the girls can stretch their legs and wings (if its not dark). Also, is it safe for the girls' container(s) to be in the trunk? I'm not sure if exhaust fumes build up in trunks. My car is a 2006 and I've never noticed fumes in the main part of the car. At times when I've had to bring the gas can to the gas station to get gas for the lawn mower, I've DEFINITELY noticed the fumes from the can while I'm driving. At first I was thinking 'I can't stuff my new girls in the trunk!', but they're already in a box or boxes. What do you think? Thanks!
