Just a little story. Yesterday, we had two 4 or 5 weeks old chicks, one black and one brown. I bought them at the local feed store 2 weeks ago for $2 each. They were living in our make shift brooder, inside our make shift feed shed. They were checked last night. All was well. This morning, they were both gone! It turned out that the cage door had a little play from side to side. When our 11 year old grand daughter checked on them last night, she must have locked them up with the door slid all the way over to one side, and a crack on the other. I had never noticed this feature of the cage. We don't know when they left the confines of their constantly lit and heated brooder, but it probably didn't take them much additional time to discover a hole in the feed shed wall. The surroundings are largely covered with a leafy ground cover. It is tall enough for our full grown hen to hide. Upon discovering the escape, my wife starting hunting for the missing chicks, calling out for them. Much to her surprise, the larger of the two, the brown chick, emerged from the ground cover and 'came home to mama.' After a brief chase, she was returned to the brooder. The black chick still hasn't been found. It probably didn't make it through the cool night. The low was 66 degrees. The recovered brown chick seems to have been very lonely, chirping and running around the brooder. After watching a while, DW decided to go back to the feedstore and get another black chick. It was from the same batch of 4-5 week old chicks, but the price was a bit higher, $2.50. When I got home, I wouldn't have even known about the day's adventures if DW had not told me about all the excitement. I'm in charge of 'structures', so I'd better fix the holes this weekend.
