Here's a little hay rack theme
This ones a freezer basket, and the pen partition it's nailed on to is an old door (cute lamb in the corner there too) These aren't great hay racks as the ewes often pull the hay out over the top, eat some and trample on the rest.
Actually these are very effective, quick and easy to fill and waste little if any hay. Oh yes, and of course the obligatory bits of baler string.
There is no way most ewes will allow a lamb that is not her own to suckle from her. The ewes are restrained and unable to move about or see the lambs. They have food and water and can lie down and stand up. Once the lambs have sucked for a few days they take on the smell of the ewe and she will accept it as hers. Amazingly this works in nearly all cases.
