I use hay as wind blocks as well. Hopefully they hold up all winter because I want to use them in the spring to start veggies early by planting them in the hayCoopchick,
I think it is so strange that the three should have underdeveloped ovaries if they came from two different sources and were different breeds. I must be wrong in my thinking that such a problem would be genetic and unrelated to nutrition. I know poor nutrition can stunt development, but can't believe that yours were malnourished as chicks! I'm wondering if the lab guy could shed more light on that...what his opinion might be.
The rest of your flock, any chickens that came from the same age group as the 3 or 4 that are laying? Am wondering if there are more chickens who "will never lay" because of underdeveloped ovaries.
I'm sorry to be so persistent, its just that your experience was so similiar to mine that I am wondering how, despite our best efforts at providing the best for our chickens, that we find these things happening!
After hearing of your results, I went out and added another feeding station. It will have to go away after the snows come, but....And I am planning on adding another shelter area this weekend so that the 10 chicks added this spring will have a place to be out of the snow and wind. Right now the underneath of the coop is a little crowded - it has haybale windblocks and the feed and water stations.
So a hen trying to stay out of everyone's way has a hard time. I have a sheet of plywood and some cement blocks...and will get some more hay. Dang, and I had other things I wanted to do this weekend@

I have found that the insulation boards work well as wind blocks. I was short a hay bale and my friend suggested using the insulation board instead. I have a ton of it that I got on clearance. I put a piece in a garbage bag so the chickens can't eat it and it has worked wonderfully to keep the winds out of the coop
