My husband and I spent the day yesterday rewiring the enclosed run we have for our 12 eight week old guineas. Yesterday was the first day they were loose in the run, no one escaped. I left them loose in the run last night, figuring they were safe. Well this morning there are only 9. I figure three squeezed out somewhere and flew out of the fenced yard. I see no evidence of something coming in the enclosure and getting them, they are just gone. I will be suring up any gap they could have gotten thru so we don't lose any more. What are the chances they will come back tonight if something doesn't get them???? We've had them out in a dog cage in the enclosed run for about a week.
