Whether or not the budgies will do well in a particular temperature, depends on whether they are acclimated
to that temperature. For example, if you take budgies that have never been exposed to extremes before, they might not survive, or at the least not feel comfortable, which can stress them enough over time to lead to illness and death. It doesn’t matter that wild budgies are from a harsh climate. If the individuals are not accustomed, they will not do well.
Do you have the birds already? Have they been gradually acclimated to the weather? If so, it should be okay.. but in the very hottest time of year, besides having a shade shelter, plenty of water provided for bathing and drinking would help. Also, if it’s possible to incorporate a misting system with a fine water spray, that would be great to add.
Meanwhile, be sure to read up on all our Stickies and Articles. There is a lot of essential information, as well as answers to questions you may have. If you still have questions after reading the material, feel free to ask.
Looking forward to hearing more about this project.
