I would make good use of that recipe you posted.

Prolific breeders? The gestation period of a guinea is something like two months, and the usual litter size is from one to four. Mine usually had just two.
Raccoons are terrible!I'm in the midst of a couple of really bad days. I don't need sympathy because I apparently didn't safeguard things well enough. Two nights ago raccoons pried a siding board off of one of the breeder houses and killed all but one hen. I'm trying to nurse her back to health.
Yesterday, I made sure everything was secure but when I went out at dusk, there was a dead cockerel in one of the open coops when I was closing it up. I don't know if the raccoons squeezed through the 2" space between the door and concrete floor or if they were hiding in the building when I closed up but this morning, every other cockerel was dead and all but 3 pullets.
When I checked the other flocks, I found all of another flock dead. Again, they pried siding boards off of the building. This is a new well built building.
In 2 nights I lost 13 mature or breeding age hens and pullets as well as 8 cockerels and cocks.
I had set 2 traps last night and they were ignored.
I guarantee I will be going over each coop with a fine tooth comb and securing anything that isn't raccoon proof.
I'm down to 19 layers from 32 and 2 roosters from 10. Only 7 of the layers are mature hens and 3 are broody. The rest just started laying so the eggs are too small to incubate.
I do have some chicks and a couple eggs in the incubator but this is my worst 2 night loss in my life.
Last year the raccoons broke into my cellar and killed 10 baby chicks.
I have my work cut out for me today to close off every tiny hole.
I guarantee the raccoons will make a good grill to provide protein to the remaining chickens.

I understand predation but I don't really get killing 21 adult birds in 2 nights and only take the head, neck and crop. None of the rest of the bird was eaten. Perhaps they were teaching cubs to kill. What a waste. This is one of the worst days of my chicken keeping life.
