I use the wire mesh office drawer baskets and just flip them upside down in the hovabator rather than making a lid or using a bag. The chicks can't move around a ton but I would think they could not in a bag either and I have not had a problem yet. I use up to three so that leaves four compartments for keeping track of single matings.In my Hovabator, the tall basket won't fit...so if i use the plastic I use the same type only shorter in height and slip them inside a onion bag. Also there are wire mesh office drawer baskets that are ready made and cheaper than the wire hardware cloth. I slip them inside a bag also. They have a mesh bottom which doesn't inhibit the humid air flow and are dishwasher safe.
My Columbian Wyandotte pullets and hens have yellow legs especially when they free range. Laying an average of four eggs a week, the leg color fades to cream when they begin molt while laying.
Out of 75 CW chicks so far this year I have saved back 5 pullets and two cockerels. In another pen containing Black daughters from the CW rooster and a Blue hen, I am getting a small percentage of black chicks with yellow shanks and feet. These chicks will be allowed to reach 3 months before I first cull unless there are noticeable faults.
