Loving, I had to laugh about feeding the excess fish to your chickens. I used to have chickens, and they loved me. I would feed them all the rotten tomatoes, stalks of corn, grubs that I found in a compost pile (the grubs were the size of my thumb, and there were over 50 of them!), etc. and I never hated letting things go to waste in the garden, as the chickens would eat anything and everything. I would sit on an upside down 5 gal bucket and some of them would literally jump onto my lap or roost on my shoulders.
The way I look at it is if you have fish that you can't get rid of, you might as well feed them and not waste them.
I'm extremely fortunate as all the fry that have lived are a total of maybe 10-15 this first year of my pond. And, there are a total of 3 black ones (the oldest of which is already orange), but the rest are beautiful, red/white or tri colored. I could literally name each one of them as they are that different. It's been a treat to watch them grow up. I can't imagine 40 of them in a 40 gallon tank! Not sure how big your 40 fry are, Brad, but my oldest ones are almost as large as their parents, which are 6-7" long. The size of my fry are 4-5" from the first spawning, (there are I think 7 or 9 of them) and the smaller ones are anywhere from 3/4" to 3".
Good luck with whatever you do with your excess! I plan to net out the short tailed goldies next year and all the orange ones, and just keep the "prettier" ones with long tails. In time, I may remove all the goldies and only have koi, but for now I'm sure enjoying the pretty babies.
