After about a week of having the feeder set partially open, then a day of having it closed (where all three completely ignored it and acted like I had starved them) the girls finally got the hang of it this morning! I showed my Dad yesterday as well and his comment was..... "I'm surprised.... I don't expect a girl to be able to do stuff like that". Pfft to him! He's an engineer... I thought he might be proud I've inherited his practical nature. Meh. I'm uploading a clip of it in action (with the chooks using it this time, rather than my kids LOL) so will post a link once it's finished uploading.
