I REALLY don't want to wether Marty, he's a real nice color, PLUS he's half Dorper

Which I think if he were left intact, he'd produce good market lambs in the future.
But I made myself a promise to wether him on Friday or Saturday if no one wanted him as a ram.
I'd keep him, but I wouldn't wanting him breeding with his sister, or MaryEllen, or something like that.
SO I'm kind of torn on what to do?
I already have one ram lamb(Samson)who I'm leaving intact. I've planned to sell him as soon as he's weaned.
On the other hand, if I wether Marty, he'd make a good meat lamb, because I'm guessing he'll be a chunky lil' boy. So I'm sure he'd be delicious!
WOW I'M RAMBLING.
So right now I guess these two are up for grabs around May/June....
AND Marty is either gonna be sold as a ram, or kept as a wether for butchering.
If Irene turns out to be good sized by October, I might breed her.
Either that or wait until May next year to breed her. Gosh she's awful small... Hopefully she'll catch up!
... I'm keeping her though, unless she stays really small.
Lol I'm trying to think ahead here so I don't end up with 20 sheep!
I need to keep it around 5-6 adult sheep... we just don't have a ton of barn room!
