This article has some really good information, especially about the signs of ammonia overload in birds of different ages. Some of the information is wordy and difficult to interpret, so some simplification would be very helpful for most readers. The sentence about "anticipate evaporative moisture losses" is hard to decipher. It may have a simple typo (should it be anticipated?), but unless the reader already understands the concept, it's kinda hard to interpret properly.
Other than that, this is a really good article, and with the quickly approaching winter weather, a very timely one! Thanks!
