I’ve tried the smaller area that only the chicks can get to with my polishes and my Baby Margo got stuck in there all by herself and couldn’t get out! She squatted all the way down to her hocks and shimmied! I had to help her!Sorry, I don't 100% agree with this. In my experience, cockerels and roosters are impatient for pullets to reach sexual maturity and often do not wait. When I had a mixed flock all the same age, it was horrible. The cockerels at about four months became so demanding that I had to separate them into a bachelor pen. The little pullets were running from them screaming during the day, and in the evening they were terrified to go into the coop, as the cockerels would go inside first and wait to jump on them as they came in. They were like muggers, to put it mildly. They all ended up in the freezer to give the girls some relief. The pullets did not start laying for about another two months.
