Sorry for the slow reply, it's been hard to check on them since they're so high up. I've been keeping an eye out below the nest and hadn't seen any jumpers so I was hopeful.
Then just now I was working in the barn and heard a ruckus of finch chick chirping. I stuck my head out and spotted the mama finch feeding at least two finch chicks based on the hungry little heads visible over the rim of the nest. I'm hopeful that the third chick is still in there too based on the sheer amount of noise that they were making

. I tried to catch a video but she was done by the time I grabbed my phone...
Thanks again for all your help in keeping these little friends alive! Cooler temps forecasted for the next week by which point the older two should be getting close to ready to fly anyway
