Our second coop was JUST made inhabitable today. No thanks to Mother Nature for her lack of cooperation this winter. I've been waiting for fertile eggs from my 3 Silver Spangled Hamburg hens, however with only one SSH rooster and 13 or so other hens, he's been a little overextended. Here's Simon: I figured Simon needed to be sequestered with the three Hamburg hens for a while. I can't keep a rooster (much longer) and I've never purposely bred a rooster with hens, so I need to know a few things before we adopt him out 1. How long should I keep the four of them confined together? 2. How long after mating do eggs become fertilie? 3. How long after having last mated with a rooster will a hen's eggs continue to be fertile? 4. The hens are bantams and the rooster is not, might he not mate with them because they're much smaller than he is? I understand there will be ranges of answers. I'm just looking for some ballpark information. Thanks in advance for your reply.
