Thanks, gale65. I may try to ask her about that if I win an auction.
I don't know if my chickens will figure it out but they were pretty smart when it came to the nipple waterers. Took them about 10 minutes to get the hang of it.
Has anyone tried making something like this and selling from the US? It is a PAIN placing a bid and then getting outbid at the last minute...especially since there are a few of the same items up for auction that have no bids! I hate when people do that.
