My MFCs are all young birds ~ under a year and not in full feather yet. Plus, because these are project birds, they do not have the perfect round rumps that we hope to acheive when the pattern is also correct. That being said, we are defintiely striving to get the best conformation along with the correct color/markings that we can as we work on the project. As far as my own flock goes (and I just got started this fall) only one of my girls, out of three, have had fertile eggs and the percentage rate has been rather low (probably 30 to 40 percent) for that pullet.
This is the pullet that I have gotten chicks from:
Now that I think about it, I wouldn't say that her cush is any smaller than either of the other two girls.
How often do you AI your flock? Do you have to gather from the Rooster for each hen or do you get enough to inseminate several girls from each 'session'?
I've seen the U-Tube video on collection and insemination ~ where the rooster is stroked until he ejaculates and pipettes are used to collect the semen and inseminate the hen ~ is that the method you use?
I really am trying to let my chickens lead as 'natural' a life as possible. Each breeding group (I have 3) has a large pen and access to outside during the warm months (I'm in MN.). My biggest group is a rooster and 7 hens and they're in a 12 X 10 stall with a door that opens to a fenced in paddock.
