Now the hay and pasture issue is a tough question for almost anyone on here to answer because of the difference in climates and growing seasons that we all experience. Are there any cow calf guys in your part of the country that you can consult with or watch?
GCreekranch would tell you that it won't work because where he is up in the high country of BC the snow is still coming - well, maybe not - but the hay sure isn't very tall yet in May!
Do you get much snow where you live out there on the east coast? That would have a big impact on how you feed hay. A bale bed wouldn't work here in Ontario because the snow usually gets too deep, sometimes even for a tractor.
There used to be an Maritimes poster on here by the name of Red Country but he hasn't been on for a while. From PEI or Nova Scotia I think?
