So, we've had our feather babies about 4 months now, and they're doing great. Both will play with us outside the cage, eat from our hands. They're eating sprouted seed and green leaf lettuce mostly. Still want nothing to do with fruit. Pasta is an occasional treat, they mostly play with it. We are headed on a long trip soon 18 hrs total drive time. I'm just wondering about covering them during the trip. Is this necessary? They've been on little trips with me before without being covered, and sing away with the radio. Any suggestions would be great. Thanks.
