I have 2 bucklings that are doing great so far, being raised by their mom. Will be 1 wk. old tomorrow. I just noticed last night that 1 of them had a bit of feces "stuck" in his bottom, still there this morning. Seems like it's just not coming out. Is there something that I can give him to just get it to pass through easily? I've noticed him look like he's straining to go, but it's still stuck Thanks!
