I have only used MHP. I love it. I use it for my incubator hatched chicks, so I keep them in the house for awhile to be sure they know where heat is are eating drinking and have no issues.
My first batch I waited until 4 weeks to put them out in dog crate with MHP but I won’t do that again at 13 weeks they are still not fully integrated with my flock. My second hatch I put out at 2 weeks (plan was 1 week but we got sub zero temperatures so I held off), it was 30-40’s during day and down to teens at night and they thrived. After a few days they were squeezing in and out of the bars of the dog kennel and mingling with the flock most of the day. My flock paid them no mind at all. But they had the safety of the the crate to get away and food and water if needed. They would go back in crate under MHP for naps and at night to sleep.
