No problem.
It is also very easy to not sex babies correctly when born. Sometimes even when they are older. There is always that mistake I made when I first started out. I didn't know why my females were not producing. I finally found out that I had collared the male. Yea, that's right - go ahead and laugh at me. Hard to produce when your chins don't have the right equipment!
Another funny for you guys - I purchased part of Carole Kessler's herd and they were quarantined at dad's place. He took care of them during the week making sure they had water and food and he became attached to one checked male - which he INSISTED on calling she... Patches was on the top row. Dad called me all excited saying, "Patches has had babies. I peeked over the top of the tray and saw her having babies. I didn't want to disturb her so I left her alone, but after I went back a couple hours later I couldn't find any babies. I pulled the tray, checked to see if she had gotten in the dust bath somehow, and couldn't find any babies there or behind the drawer. The run is blocked so they couldn't get up there either!!! I don't know what happened to the babies!"
Yes, I just let him go on while I was trying to hold in my laughter. Finally I asked him, "Dad, don't you remember I told you Patches was a male?" LOL - he was so upset and he wanted to see those babies so badly... I'll never let him live it down. Well I'm sure you all know that Patches was servicing himself and dad expected babies!!! I called and told Carole and she got a big laugh out of it too! Oh, what funny creatures these chins are!
