Yes the boys have joined the main flock and are enjoying themselves. They get along really well, also. They have 16 girls between the 2 of them, which seems to be enough to keep them from being too competitive, though the white one is in charge. They sleep next to each other at night.
These chicks should be 12-16 weeks before it gets super cold, so I think we're ok. I get worried about eggs/chicks in February because I like to have my new layers start laying in August and February can be so cold for new chicks.
I also have a set of 8 chicks that are 8 weeks old right now that are slated for freezer camp at about 16 weeks, so we won't have to worry about feeding them over the winter. We are trying to produce about 50% of our food from our property. We're not there yet, but we are getting close.
we have 25 meat chicks born the last week of August, first week of Sept. We figure we will take them in for processing the last part of October depending on how fast big they get. This is our first time with Cornish X chicks. We are giving them feed for 12 hours, water continuous. We have them able to enjoy the grass, jump and fly about to develop their muscles. Don't want to just get little butter pats to cook

. That plus a quarter grass fed beef order every fall and we have our meat pretty well figured for the year...well, I am sure we will need to supplement the chicken and this 25 is our test bunch.
