Hi,
Your young buck likely couldn't have reached this big doe, even if she would have "LET" him

So we can't go by that. Now you have a new buck who traveled a very long time to get there, stressed to the max, and now is breeding does, he may have had no semen even left to breed her, how many did he breed in a 48 hour period? All 3

I would definetly get her in the pen with him now, is she at 21 days from her last breeding? Beware also there are hussies who simply have heats for the first 21 day period or sometimes 2, are bred on subsequent heats, only to kid on the first breeding....they don't read the same books we do!
With her continued milking I would doubt she is bred, least wise not bred for any length of time, unlike your other doe who is showing you she is bred by her non-exsistant milk supply.
Can't they just drive us batty at times!
