Aoxa maybe is you put the frozen water bottles in the bunnies fav shade places they would be able to lay next to them and help keep cool? Sorry you lost your bunny. Tis heat has been horrible.
Mumsy thank you for sharing your pictures. I'm sorry you had to cull her but it was the best for her since she was deteriorating.
Last night I had flies in the FF even with a cover on it. Those nasty things burrowed in the food. I got them all out and put a temporary netting over it
I'm going to sound like a broken record (do you young folks know what that means? ) But... If you do the ferment as for lacto-fermenting with the layer of water over the top, you won't that that kind of issue.
I'm old I know what a broken record is
This time of year I try to keep more water on top but the chickens like it thicker so I am trying to reach a happy medium. Tough with crumbles to keep more water in it but not make it soupy. I added more water but those pesky flies were still in it. I think its just cuz it's so darn hot !!
