Hi and welcome. I am a former Ct and Vermont Yankee moved to Va in 1981. My parents retired to NH although are getting up inage and health concerns for my mother. But they will never move away from up there.
I did talk to them and they had as bad a year for trying to make hay as we did here in Va. Way too wet, very few breaks where we had 3-5 days of dry to make hay. It was all made "late" quality wasn't great, but it got made.
I would get some of the orchard grass/alfalfa and see if they like it. And a bale of the "brown" hay. We actually made a field of orchard grass after we had 8 inches of snow on it in late Dec. It tested at 12% protein and the calves eat it with no problem. It was "cured on the stem" freeze dried actually. Figured that a little supplement with feed would be better than nothing. As the saying goes here, " it beats snowballs".
Stemmy alfalfa winds up with alot of waste. Most farmers here will chop 1st and 2nd cuttings, then the stems are not near so thick and tough and we try to get about 150 sq bales a year for the sheep and for my nurse cows. I'd rather feed it as baleage but don't know if the sheep or goats or smaller ruminants should have it. My nurse cows and calves love it.
Timothy is a very good hay. I like it better than orchard grass, but it doesn't do good here because it doesn't like the hotter summers. Of course this past year it would have been well watered. We had nearly twice our normal rainfall last year. It also doesn't seem to be letting up. Have had twice the normal already to date.... don't want a drought in July/Aug but sure would like a little less right now. The fields are a disaster and just getting around to feed is a nightmare.
I would go see about the timothy. If it looks good and smells decent, then I would get it. We don't test all our hay, and many farmers don't. You get to where you can look at the animals and get a feel for their nutrition level. But testing the hay was important this year because we have some that is way low, and we are having to supplement with both energy and protein for the calves. At 6.00 a sq bale, that is pretty reasonable. I would buy 500 bales if it was available here.
They need bulk, roughage. It is cheaper if the hay also tests good, but you can supplement and it doesn't have to be alot. Since you are milking, give the doe what she needs on the milk stand; give the others a little grain as a supplement, and feed the less expensive hay. It is only for a few months and then hopefully you can find a farm close that you can maybe pick it up out of the field, or off the wagon and get a better price. Get enough timothy to see you through if it is decent, get a few of the orchard grass mix for extra protein for the doe... limit feed it so they clean it up in an hour or two, and then let them have the other hay. Don't be surprised if the timothy is decent and they like it better.
