Chelle - Thanks.
After breeding canaries for a few years, you understand the fact that cleanliness = healthy when it comes to birds (and everything else!). I feel guilty that they're in such a small tote but they don't seem to mind it too much. Next week they'll be moved into a 55gal aquarium (4'x12") where they can get sunlight rather than just incandescent & heatlamp. But they'll still have their heatlamp to make sure they don't get cold.
Do you think they can be OK in 65-70deg temps now or do I need them to be fully fledged before they can handle temps that cold?
