Fun topic, actually been thinking this over since start of lambing.
Agree with Head Lamps, makes doing chores so much easier with hands free in the dark. Just got a couple new, rechargeable ones, and they have awesome light range for less than $25.00
Lamb cradles from Premeir. My husbands favorite
Lamb warming barrels. First time using this year. Makes warming up lambs that need a little "extra" much easier. Ewes have accepted them very well.
Baby buggy. My husband made a ewe hauler that he can lift with pallet forks on bobcat. Enclosed a corner for lambs, so ewe can see lambs but not step on them when being transported.
Microwave lamb warmer. Not sure of proper name. We got ours from Nasco years ago. Warm up in microwave, wrap around chilled lamb. Have revived many a lamb.
Lak Tec milk machine. Third year using and still am in awe of how it has changed our "bonus" lamb program.
Lamb tuber. Have utilized protocol of tubing colostrum immediately to new lambs, mostly of multiple births or born when cold. 4 oz gets a lamb up and moving.
Hay feeders for lambing pens. My husband has been building these, one wooden feeder feeds two pens. We use small bales at lambing time, one flake fits in a feeder side, cuts down on hay waste.
