Thank you, that was actually my questionI realize you've had 900 comments after this, but I skimmed through and didn't see anyone mention a fecal. You really need to get a fecal done (you didn't mention if you had) prior to worming so you know which wormer to use. Not all wormers are designed to kill all parasites. You can send them in for $5 a sample to www.midamericaagresearch.com. They can also test for coccidiosis.
That being said, I will agree, I don't see anything wrong from this angle.
Also, is your boy a wether or intact male? If he still have his testicles, they need to be separated as your girl is probably too young to be bred.

I will look into sending a fecal in. He was obviously not well taken care of wherever he came from originally, which is why I was concerned. The little girl had clearly received better care.
They are only about six months old....is breeding an issue at that age? I planned to wait until he was a year old to have him castrated, since I read that wethers had more urinary problems if they were done early.
