I'll keep the pine tar in mind.
The only treats I give them are salad fixins like cucumber, carrots, tomatoes, celery, lettuce (I never see them eat the lettuce though. They don't really like green things except grass). Sometimes green beans. They aren't a favorite either. They only get treats 2-3 times a week. I have some plain yogurt on hand. I'll give them some of that, too. The five of them just gobbled up 1/8 lb of burger.
I have a litterbox in their run with just the DE in it, but they aren't even looking at it yet. I was thinking of picking at the frozen ground and trying to get them some dirt in the box too, but I thought it might negate the drying qualities of the DE if it was mixed in with wet dirt.... What do you think?
And I just pulled five eggs out for the day, so whatever it is isn't slowing down their egg laying at all. Two of the eggs have purple on the shells. Hmmmm, wonder who layed those .... and one of those was coated with small feathers, so the feathers are still falling out or being pulled out.
